I received access to this web site today and found it very interesting. You probably don't remember me, but I did run into you from time to time over the years I worked on MATCALS at Mare Island. I worked with Gordy Erickson and managed the software development work on Mare Island for MATCALS. After the island closed in September 1995, I commuted to San Diego for 5 years, continuing maintenance of the MATCALS software until I retired from LM in 2000. After that I have continued to support SPAWAR in San Diego on a part-time consultant basis. Even now I am just finishing an 8-week task in January with what I believe will be my last support of MATCALS. Yes, MATCALS is still being supported by Lockheed Martin (LM) in San Diego by two programmers and a field engineer.
MATCALS is still being used by the Marines in Iraq and elsewhere
with 1980 technology. The latest software update brought MATCALS
TADIL-B up to the current standards. Sperry, Unisys, and Lockheed
Martin built a great system that still has not been replaced by a
"modern" ATC system, so the Marines continue to use MATCALS and
SPAWAR is continuing to maintain it. It still uses the original
AN/UYK-44 embedded computers, but has had the FOG display replaced
with a new display. It is expected to be fielded for at least
another five years before the replacement system is fielded. As you
know, "the company" built the TPS-70 ATC radar, the CCS shelter,
MMDs, computers, and software for MATCALS. The only piece of the
system built by another company was the TPN-22 final-approach radar.
I find it remarkable that the system originally fielded in the mid
1980's is still being maintained and used. All who worked on MATCALS
hardware and software over the many years built a great system that
is like the bunny that just keeps going and going and going. The
SPAWAR Systems Center in San Diego is maintaining the hardware and
as I said, LM is still supporting the software. I hope someone can
provide more info about MATCALS for the web site.
There should be some retirees in your group that can provide good info
on MATCALS. I look forward to viewing additional info on all that you
have planned to be included. Yours in retirement from LM, Ron Irwin

The Field Engineering Department of Sperry Univac Defense Systems hired me in February 1965. Specifically, to support the Apollo Space program, that was just beginning. After some basic training on the type 1218 and 1219 computers and peripherals; I started working with the design engineers Bob Oulicky and Don Mager doing design test of the new 1230 computer which was designed specifically for the Apollo Project. Reference http://vipclubmn.org/CP30bit.html#Type1230.
In October 1965 I was sent to Goddard Space Flight Center with several other engineers to provide technical support to NASA personnel as well as to the 100+ Univac on site programmers. Six months later I was promoted to be the site supervisor; a position that I held until requesting a transfer in December 1971.
At peak time we had 12 Apollo Project support engineers, half of them on various sites around the globe. Shown here are scans of two of my four Apollo mission support certificates.
In December 1971 I was sent to Germany to provide technical support to the German Navy and to the programming team at the Wilhelmshaven Naval Base. We were working on development of the Fast Patrol Boat system. I stayed there for nine months then moved to Bonn/Bad Gödesberg.
There I provided systems engineering support to marketing. At the right is a 'Tiger Award' from VP Dick Seaberg for the German Navy Link-11 system. In Bonn, I also lead marketing initiatives for southern Europe and the Middle East.
In 1976 we won a successful contract with the Greek Navy,
The Greek Submarine Program. This was the Kanaris
submarine fire control system. I was sent to Greece to be the in-country marketing
representative for Greece and the middle east, interfacing with the
Greek government, etc.. At the left is recognization by VP Jim
Rapinac.
18-years later, July 1994, the Company brought me back to St. Paul
to work with various marketing teams -
then was laid off in March of 1996.
This may sound as an uneventful career; but for me it was very exciting and challenging. I had opportunities to work on some interesting projects like the Apollo Project and to work with many very capable people. I believe I left a good name with those co-workers who got to know me. Since leaving the company in 1996 – have kept in touch with former co-worker Keith Myhre, (http://vipclubmn.org/People5.html#Myhre) et al’.
Background: I was born in Greece but immigrated to the US at age 17. I became a US Citizen, then went to college at the University of Illinois, graduating in 1964 with an Electrical Engineering degree.

Like so many at Univac I grew up on a farm, got
a technical degree from the state university, and found myself working
in the new field of computer technology at Univac. However, instead
of being from Minnesota, the Dakotas, Wisconsin, or Iowa; I grew upon
a horse and tractor on the high-plains of Western Nebraska. Our family
farm was split between raising cattle and wheat.
Growing up in a rural area usually meant that you attended a small high
school. I had eleven in my high school class and went from there to
the University of Nebraska, receiving my BSEE in 1965 and MSEE in 1966.
After the University of Nebraska I went to Officer Candidate School,
becoming a second lieutenant in the USMC. The Marine Corps wanted me
to go to the infantry; however, I thought I could make a better contribution
if I could use my EE training. Although the folks making the assignments
could not provide any assurance they did assign me to a Marine Air Control
Squadron at Camp Pendleton. My unit was in the process of rotating back
from Vietnam and we were reforming at Camp Pendleton with all new computer
driven equipment. At that level we were users and not developers, and
I became an air intercept controller using the computer processed radar
information to guide fighter pilots into the right position to shoot
down the enemy fighter.
In the fall of 1967 the
executive officer calls me into his office one day and says, “Lieutenant,
we have a quota to send someone to programming school and you are the
only one qualified.” The catch was an agreement to spend three
years on active duty after graduating which meant an extra 15 months
of active duty. I agreed and found myself at the Fleet Computer Programming
Center, Pacific in San Diego learning all about and how to program the
Univac CP-642B and its Marine Corps version, the CP-808.
After graduating from programming school I was transferred from Camp
Pendleton to Marine Corps Air Base, El Toro in Orange County California.
I was assigned to another Marine Air Control Squadron to work on a project
called the Southeast Asia Interface. As it turns out the Marine Corps
had the only system (the AN/TYA-20 from Univac) that could be programmed
to perform functions similar to a modern day router, linking all the
air defense systems in Vietnam together. The project was well underway
and I became the third member of the programming team. The other two
members of the team soon left and I became the principal programmer.
I felt very fortunate to be assigned to a technical job doing data communications
programming for the Marine Tactical Data System.
This
project was built and tested with the Air Force and Navy in Southern
California and then deployed to Vietnam. Doing the programming was the
easy part. Getting the resources was the challenging part. I was lucky
again, the gnarly, well-respected maintenance chief was CWO-3 Dante
A. Massarotti and one of his bright young technicians was SSgt
John Westergren. Gunner Massarotti and the electronics officer
went to the Navy and extracted a junked RD-243 magnetic tape unit that
they refurbished. This was a great improvement over paper tape.
In addition, the Univac field engineer, Dennis Angel, taught me all
about DS-4772 and how to program Input/Output (I/O). In order to compile
our software we either had to drive to FCPC in San Diego or drive up
to Pt. Magu. Many times we would go to Pt. Magu when they were not supporting
a missile shoot and work all night. Eventually we were able to get a
driver with a security clearance and we would send him to San Diego
and have him wait for the results.
The program was deemed fully
operational in the spring of 1969 and we took it to Vietnam in June,
making it back in time to watch the lunar landing in July 1969.
After successfully deploying the software I received my orders to return
to Vietnam for a year long tour. Unknown to me, the commanding officer
of my unit thought that I could be more useful to the Marine Corps if
I were able to apply the lessons learned from the Southeast Asia Interface
project to the emerging data communication standards for Air Command
and Control. My orders were cancelled and I spent my last year of active
duty doing a small part to establish the Marine Corps Tactical Systems
Support Activity as the Marine Corps center for tactical command and
control systems.
With my tour of duty approaching an end I decided
that I would not go to work in the defense industry and was able to
secure a system engineering position with Electronic Data Systems (EDS).
I thought that I was headed for their data center in Dallas, TX. Halfway
from Southern California to Dallas via Nebraska the folks at EDS contacted
me and wanted me to go New York City instead. That did not appeal to
me and after some discussion I ended up on Des Moines, IA. The job was
not technical at all and one I did not like. So, I called my friend
Danny Massarotti and asked him if there were any jobs at Univac.
He thought there might be one and fortune smiled once more with a Sr.
System Engineering position in Ground Systems at Univac Defense Systems.
July 1971 was the start of my seventeen-year
career at Univac Defense Systems. I had already been programming Univac
computers for several years and felt right at home. The company was
at the leading edge of technology, a good place to work, and I enjoyed
the people.
This time frame was the dawn of the
sixteen bit computer and I helped put together the AN/UYK-20 winning
proposal that eventually led to my first project engineering job, updating
the AN/TYA-20 from the CP-808 to a cluster of four AN/UYK-20 computers.
The CS-1 code used in the CP-808 was updated to CMS-2 and we employed
MEANS statement to fully embrace structured programming constructs.
Since we had very limited space in the shelter we had to find a way
to use a single set of peripherals. Ethernet or Token Ring was not yet
available so engineering developed a shared bus device called the Data
Bus Controller or DBC.
We had a requirement to
interface with different types of serial communications that in no way
resembled commercial communications, eliminating the use of any off
the shelf commercial chip set. Glen Kregness came to the rescue with
a variable character length serial interface that was to be known as
VACALES. {Editor's note: Glen created the concept, Dick Erdrich did
the basic hardware logic design.}
As we were
getting to the end of the project the IBEW was in contract talks and
threatening to strike. That had the potential of preventing us from
delivering on time so the decision was made to ship the shelter to Camp
Pendleton (MCTSSA) and finish the software there. The challenge of finishing
on time was increased significantly, especially when we discovered wiring
errors. We finally did finish and the Marine Corps accepted the system.
The next big event was the MACCS-85 project.
This was the next generation air command and control system for the
Marine Corps. The company made a very large commitment to this program,
developing a strong team. I don’t think I’ve ever been in
such a large and close-knit team that worked grueling eighty-hour plus
weeks for two years. We had the right technical approach and the Marine
Corps liked it, but we did not win. I’d like to go back to the
evaluators and ask them to eat their words about our pricing. They dinged
our proposed display pricing because they felt we did not provide sufficient
justification for reduced semiconductor memory cost in the future. This
was one of the most ridiculous reasons ever. Lower semiconductor memory
cost has enabled a wonderful array of products like laptop computers,
iPods, digital cameras, and cell phones.
We might
not have won MACCS-85, but we set the stage for our next large contract,
the Marine Air Traffic Control and Landing System (MATCALS). The first
competitive procurement between MACCS-85 and MATCALS was winning the
Multi-Mode Display or MMD. That win, combined with our air traffic control
experience, NTDS, MTDS, SHINPADS, etc. positioned the company to win
the MATCALS program. This was one the first large command and control
systems with embedded computers linked by redundant serial buses. For
Sperry Univac it became a real showcase for switching, displays, communications,
distributed computing, etc. It also put Sperry Gyro in a good position
to win the air surveillance radar contract for MATCALS.
After so much time in Ground Systems it was time for something different.
I moved into Airborne Systems and worked special programs. Here is what
I can tell you about that experience _____________________________.
Let me just say that it was enjoyable and I thoroughly enjoyed working
with the airborne team. Everyone who worked special programs got to
know Ernie Ryan. {Editor’s note –
Ernie took care of security clearances and associated
facility access.} He ran a tight ship and it was fun for a former
Marine to link up with retired Navy guy. We even got along.
After the merger with Burroughs and the birth of Unisys I decided to
take a look outside the company. Sid Rundell had successfully ventured
out of Univac - I joined Sid in Lockheed Missiles and Space, Austin
Division. Shortly after I moved to Austin, Sid was offered the GM position
in Salt Lake City and I replaced him as the Director of Business Development.
Lockheed was much like the old Univac with great technical talent, always
on the leading edge of technology. The late eighties was the start of
the decline in the defense industry and there was not enough business
to support the large facility Lockheed had built in Austin.
In 1990 I could see what was happening and moved back to the Twin Cities
to work for a small high-tech commercial company, Ancor Communications.
After some entrepreneurial efforts and start-up management positions
at NEO Networks, NuSpeed, and Cisco - I retired in early 2003.
Lady luck has been nice to me throughout my career. I’ve always
had the opportunity to work with some the best and most talented engineers
and the companies I’ve worked for have been technology leaders
great at operations. The softest spot in my heart is reserved for all
my friends and co-workers and Univac Defense Systems. We were a bunch
of raw but talented folks who conquered the new world of high technology
and did some amazing things. I can’t wait to see what the next
generation will do.
My original position at Univac was as an engineer
in the Process Control Research group in the Research Division, headed
by Dr. Leroy Stutzman. The Research Division had four departments:
Physics, headed by Sid Reubens; Math Research, headed by
Arnie Cohen; Process Control, headed by Jack Tierney; and a
Systems Department. The goal of the Process Control group was to research
the potential for computers in the analysis of chemical processes and
ultimately for process control. The analysis part was successful, but
the control part was premature. Computers in those days failed about
every few hours and chemical processes could not be allowed to fail
even over a period of two or more years. We had a great group: manager
Jack Tierney, Dale Ruud, Chuck Homan, Bob McCarter, Jim
Nikitas, Curt Brasket, and myself. Dr. Neal Amundson, head of the
Chemical Engineering Department at the University of Minnesota, was
a consultant. After a few years, the Research Division, except for the
Physics Group, was closed down as not profitable, and the staff migrated
to either other parts of the company or to other careers. We had published
papers on digital control and chemical process models, but could not
generate serious industry interest.
I joined
the Navy NTDS project as a section leader of a group developing algorithms
for military interceptor and AA missile control systems. Other projects
involved algorithms for the SPN-42 Automatic Carrier Landing System.
We used the Univac 1103 computer for our analyses. In this period I
had to travel extensively to various Navy facilities: Washington, China
Lake, Newport News, San Diego, and Los Angeles. In 1960 I spent a week
or two on an aircraft carrier (probably CV-62, the Independence) for
observing command and control and air operations. We planned to computerize
them in NTDS. During the ride a hurricane came up and the big ship really
bounced around. The carrier was summoned to aid a passenger ship that
had a seriously ill passenger. I remember going up to the deck and being
completely disoriented since it was totally dark—no horizon and
the ship was operating under battle conditions with no lights. I could
not even see the deck. I learned a lot about Navy customs and etiquette.
I made the mistake of showing up for dinner without a tie and suit—no
one would speak to me. Dinners in the officers’ mess required
suits and ties. We bunked in the pilots quarters that were under the
flight deck so it was pretty noisy, especially when the catapults were
operating. I was able to explore the entire ship. The chain locker impressed
me. This is a gymnasium sized room where the anchor chains are drawn
up. A link was about waist high on me. The scale was hard to believe.
The steam catapults were improbable designs but worked very well.
Other projects included developing algorithms
for missile tracking ships and for a tracking station on Ascension Island.
Some of my people had to go there but I worked that project from St.
Paul. Univac opened a branch office in Cocoa Beach, FL to support the
Cape Canaveral Launch Facility. I managed the facility from St. Paul
but we had a local manager on the site. We had about 40 programmers
there but the productivity was far less than that of the 30 or so we
had in St. Paul. The staff there was not as qualified for the tasks.
We solved the coordination problems by temporarily relocating key staff
to Cocoa Beach. I was always impressed when a rocket was launched. The
noise, especially in the low frequencies, was terrific.
In 1962 I left Univac to join with Leroy Stutzman in a new
startup, Tronchemics Research, Inc. with the goal of researching computer
applications for the chemical industry.
Univac’s Radio Guidance of Missiles at Vandenberg Air Force
Base
I joined Univac as a programmer in April
of 1964 and was assigned to the real time missile guidance group in
Bob Hanson’s organization. Ed Solheim and Bob Russell were the
two managers in the organization and my immediate supervisor was George
Smith. The real time programmers in the group worked on the Athena computer,
which I was to learn was probably the most reliable computer ever built.
I attended an Athena programmer’s class although I never got to
write any guidance programs for the Athena.
The
Athena was originally developed to provide guidance to the Titan I Intercontinental
Ballistic Missiles (ICBM) that were housed underground. The guidance
computer needed to be extremely reliable but did not require much versatility
since the guidance equations were fairly simple. Targets for the ICBMs
were known in advance and implicit guidance equations (fly a wire trajectory)
were sufficient to get the job done and guide the missile to the target.
The program was stored on a large revolving magnetic drum that only
had room for 8K of instructions. There was a small “scratchpad”
memory for data. It contained 256 24-bit words of rewritable core memory.
One of the biggest challenges in Athena programming was spacing the
instructions around the drum so they would be under the read head at
the proper times. A basic instruction time was 40 microseconds and the
various instructions would all be some multiple of 40 microseconds.
Programmers developed the instruction spacing program on another computer.
The early space programs from Cape Canaveral and Vandenberg Air Force
Base used the Athena as the guidance computer. However, as missile guidance
technology evolved toward explicit guidance equations, where all the
targeting did not need to be done prior to launch, the Athena could
not provide the needed capability. Thus, the move toward more general-purpose
computers became the next logical step. This would lead to major changes
in philosophy as well as hardware and hardware interfaces.
Philosophically, a general-purpose computer meant that programmers could
very easily change the program in the computer’s core memory,
so many security processes needed to be developed to insure the integrity
of the guidance system. The hardware changes were extreme since the
new computer and all its peripherals would be much smaller than the
nearly 400 square footprint required by the Athena’s large cabinets.
Also, a new interface needed to be developed to tie the general-purpose
computer to the ground radar system. Univac engineers developed a small
(about 3 feet by 3 feet by 1 foot) Radar Interface Unit (RIU) that effectively
made the computer change transparent to the radar.
An Athena computer also guided the Air Force Program 437 on Johnston
Island, but the follow on program, Program 437AP, needed more sophisticated
guidance equations, and it was the first radio controlled ground guidance
program to be written on a general purpose computer. In late 1964 or
early 1965 a small group of real time programmers was assigned to develop
the new guidance program on a Univac 642B general purpose computer.
The small group consisted of Paul Becvar, Steve Chodos, Wayne Hiller,
Dick Kistler, Don Neff, Dick Olson, and Wayne Walther. We were given
Special Access clearances and sequestered in a small office area of
Univac Plant 1. The team not only programmed the real time guidance
equations per a specification from another contractor, but also designed
and developed the real time executive that would control the program
and interface with the new RIU. The team also designed and developed
the non real time support software that was needed. All the real time
software was written in the CS-1 assembly language. The assembly language
programming enabled more efficient programming and (we believed) more
reliable programming that could be more easily debugged.
Shortly after we finished the Program 437AP programming we were given
a new task: to develop the guidance program for the Air Force Program
110 (a Titan IIIB booster and our Agena D upper stage) which would be
launched from Vandenberg Air Force Base (VAFB), CA. It was going to
be a much larger task than the 437AP task so the team was expanded by
the addition of several programmers: Larry Buhr, Ron DeMars, Bob Homyak
John Neeson and Jack Pittenger.
Starting in the
fall of 1965 the Program 110 programming team worked out of offices
in Univac’s Plant 1 in St Paul but spent considerable time in
Plant 5 where the computer system was setup. Members of the team who
developed the non real time portions were able to use the computer center
in Plant 1.
In December of 1965 Univac management
informed us that they were going to establish an office onsite at VAFB
and would be staffing it with the Program Manager and a staff of programmers.
It was to be a two-year semi permanent move with plans to return to
the Twin Cities at the end of the period.
The
team continued developing the guidance program and all the support software
until late February of 1966 when Charlie Gardner, Program Manager; Dexter
Pehle, Systems Engineer; Harold Tuset, Programming Supervisor; and six
programmers relocated their households to Santa Maria, CA. The programmers
who moved were: Larry Buhr, Steve Chodos, Ron DeMars, Bob Homyak, Dick
Kistler, John Neeson, and Jack Pittenger. Other members of the Program
110 team made prolonged trips to VAFB to help develop and debug the
software in preparation for a planned July launch. Dick Olson spent
almost all of the following five months (March to July) on site although
he did not move his household.
In addition to Univac the Program
110 guidance team consisted of Lockheed Missiles and Space Company (LMSC)
(Sunnyvale, CA), Bell Telephone Labs (BTL) (Greensboro, NC), and Western
Electric Company (WECO) (Winston Salem, NC and VAFB). LMSC, under the
guidance of Bill Chapin, developed the trajectory optimization software
that would provide the ideal trajectory for the launch. BTL, under the
guidance of Bob Tarrant, developed the explicit guidance equations that
would use the targeting information and provide the guidance commands
to be sent to the missile. WECO was the guidance station integrator
and provided the ground radar system as well as the antenna and radio
guidance box on the Titan IIIB.
The months of
March through June were a very intense period of final development and
checkout for the Univac programmers at VAFB. Everyone spent up to 12
to 14 hours a day, seven days a week, except for Easter Sunday, getting
ready for a late July launch date. Bob Tarrant was onsite for several
months as the equations were also being debugged using the WECO analog
simulator with the ground radar system. Also present were Del Driver
and Herb Lewis, two members of The Aerospace Corporation from El Segundo,
CA. As the technical advisors to the Air Force The Aerospace engineers
asked all the necessary, penetrating questions and evaluated reams of
data to ensure the guidance system was working properly.
Finally, in late July the guidance system was declared ready to support
the first launch of the Titan IIIB, Agena D. On launch day the countdown
was delayed for many hours as the launch team solved one booster/payload
problem after another. The guidance station was located under ground
in a former Titan I launch facility with no view of the outside or the
launch pad. Most if not all the programming team were present in the
guidance station in the unlikely event that they would be needed to
solve some unforeseen problem. Once it became obvious, after hours of
holds, from the countdown network audio that we were finally going to
launch in a couple minutes Harold Tuset and I went outside the complex
so we could view the launch. After all, we had seen countless simulations
and knew what everything looked like in the guidance station computer
center and we wanted to see the Titan liftoff, even though the launch
pad was about 10 miles from the guidance station.
As we stood on the hill above the guidance station without a worry in
the world, we soon realized that more than two minutes had passed and
we were probably in another hold situation. Then we heard shouting coming
from the tunnel leading to the guidance station: “Tuset, we need
you in here.” “Kistler, we need you in here.” Then
came our most embarrassing moments and probably career low points. After
all, Univac had never had a problem that caused a launch hold or a launch
failure, but we were informed that our guidance computer had just caused
the launch to be held.
To insure the integrity
of the software we had designed a feature in which the computer would
perform a checksum of the guidance program when the guidance system
was switched into launch mode. When the WECO guidance control officer
placed the guidance station into launch mode the computer dutifully
performed its checksum and, unfortunately for us, detected a checksum
error. This was not a problem that could be quickly solved and the decision
was made to scrub the launch and try again another day.
It did not take much analysis for us to find the cause of the checksum
failure. Using a technique we called core dump comparison, in which
we compared the entire core memory of the computer after the problem
with the core memory of the computer when it was loaded that morning,
we quickly found one instruction in the guidance program that had picked
up an extra bit.
Since timing pulses, data
and action interrupts from the RIU drove the real time executive, we
had decided to have the executive sit and wait in one place for the
interrupts. We did this by putting in an instruction that jumped to
itself, thus the program would cycle on the one instruction until it
needed to take action to process the next interrupt. During the many
hours that day that the guidance program was just cycling, processing
interrupts and waiting for the signal to go into launch mode it probably
spent 95% or more of that time executing the single jump to itself instruction.
As we found out later, the repetition caused that particular circuitry
to heat up and eventually the instruction picked up a bit that then
caused the checksum to fail when the launch mode was initiated.
Once we were able to point out the location of the additional bit and
explain the executive’s software design to the hardware engineers
they quickly deduced the overheating problem. They replaced the card
that had failed, we modified the real time executive to loop through
about ten instructions while waiting, and we reestablished the guidance
program software integrity to everyone’s (our Air Force program
office representatives, the Aerospace engineers, and the WECO guidance
station integrators) satisfaction. A couple days later on July 29, 1966,
we successfully guided the first Program 110 payload on its way to orbit.
That, as far as I know, was the only time
that a Univac ground guidance system was responsible for a launch hold
and it never was responsible for a launch failure. We continued to successfully
support Titan IIIB launches at a rate of about one launch every six
weeks for many years.
Not only did Univac
provide years and years of successful support but the information on
one of the guidance system peripherals was used to save a mission. One
of the guidance computer’s peripherals was a 30-inch by 30-inch
Milgo plotter. Prior to every launch the guidance program would run
the nominal mission and plot the expected flight trajectory on the Milgo
plotter. We displayed two plots: the downrange versus the cross range
plot and downrange versus the altitude plot. We would plot the nominal
trajectory plots in green ink and then plot the real time (whether it
was a simulation run or a real launch) in red. These plots were very
useful in the analysis of various dispersions during simulation runs
and the plots gave a real time view as to how well the missile was following
the nominal trajectory during an actual launch.
One day during the last two minutes of a launch countdown the final “go”
or “no go” decisions were being given on the audio network.
When the Launch Control Officer went down the list asking for readiness
from the booster, the payload, range safety and the guidance system
everyone said they were “green” except the Range Safety
Officer, who said the range was “red.” There had been a
power failure in the range safety system and the Range Safety Officer
had no information available from the range safety radars. For whatever
reason the Launch Control Officer did not acknowledge the “no
go or red” condition from range safety and cleared all systems
to proceed to launch. The Titan lifted off and proceeded nominally toward
orbit. It was the prerogative and probably the responsibility of the
Range Safety Officer at that time to send the destruct command and destroy
the missile and its payload since he had no visual information as to
the position of the missile. However, as he did during every launch,
the WECO Guidance Control Officer stood in front of our Milgo plotter
and gave a “play by play” commentary over the network as
to where the missile was with respect to downrange, cross range and
altitude and how close we were to the nominal trajectory. The Range
Safety Officer had enough faith in the Guidance Control Officer and
our trajectory plots that he let the Titan continue on to orbit. A day
that could have ended with a failed mission instead ended with a successful
launch thanks in part to our trajectory plots.
In the late 1960’s another major missile program development effort
was being planned for VAFB. That was the Air Force’s Program 467,
which was to be launched on a Titan IIID. Charlie Gardner had visions
of an expanded role for Univac for Program 467. For Program 110 all
the trajectory analysis, trajectory optimization and trajectory design
work was done by LMSC in Sunnyvale, CA, under the direction of Bill
Chapin. Charlie thought that if he could lure Bill Chapin and his key
people away from LMSC that the Air Force would be willing to give Univac
the trajectory contract as well as the guidance program contract. Charlie
successfully hired Bill Chapin and his key staff members: Dick Kallaus,
Jamie Lavios, and Ed Tilford. B ill then hired Bill Exely, who had worked
with NASA in trajectory analysis and simulation design for the Saturn
V moon rocket.
With such a talented staff
of trajectory experts working for Univac at VAFB the Air Force did indeed
give Univac the Program 467 trajectory contract. For a period of several
years the level of development at VAFB was at a very high pitch as 1230
computer systems were installed to support the Program 467 trajectory
optimization and design and the new guidance program development. All
the effort culminated in the successful launch of the first Titan IIID
on June 15, 1971.
During the first few
years after the Program 467 development efforts concluded, many members
of the programming staff and all the key members of the trajectory development
staff relocated to Univac’s offices in Sunnyvale or St. Paul or
left the company. Univac however continued to provide support at VAFB
to both the Titan IIIB and Titan IIID for many years. The final launch
of the Titan IIID occurred on November 17, 1982 and the final launch
of the Titan IIIB/Agena D occurred on February 11, 1987.
So many things that went on, that one could write
volumes
I started with the old Education department in December 1973.
I had some great people to work with. Names at the time were Ken Boehm
(deceased), Gary Hagen, Dan Newton (Mgr), Don Kimball, Mr. Engelke,
Paul Burley, and of course many others. It was a great place to work.
We got the job done and even had fun along the way. I must say that
I appreciated the help and support that one received at the time.
One can even remember many of the things
learned. I can recall working on a topic that was part of something
listed in one of the items mentioned in the sample viewgraphs that you
provided was the 1652 Dual Display console. I did most of that work
at Air Force bases. What I did not realize at the time was that I was
doing state of the art graphics programming before it was common. That
was a real personal achievement. Now with all the PC’s and packages,
it’s not the big thing that it was at the time. Back then, one
had to actually code in assembly language to make that happen.
Looking at funny events along the way, and we all had our share of them,
makes me think of one in particular. I was conduction an AN/UYK-20 Programming
class at NUSC in New London, CT. (The facility is no longer there -
it has been torn down and replaced by a Pfizer facility.) Anyway, it
was a very busy week and Friday afternoon had finally arrived. Now in
those days, there were no CD’s or anything like that so we carried
all these technical documents with us. I was starting to summarize and
also pack up boxes of reference documents. Now we would tape these boxes
up, label them, take them to the airport with us and ship them along
with our checked baggage. Well anyway, I had just put these manuals
in a box, taped it up and was getting set to finish when a person raised
his hand. He asked this question with very serious look and with determination.
The question was “Does the UYK-20 have a Pie Cost? Well, when
you hear that, you think Pi (as in circumference stuff). Upon hearing
this – remember the look and the sound “Pi”, I started
checking. Well the first thing that came to mind was that they had recently
come out with the Math Pac option for the UYK-20 and I knew that there
were trigonometric functions in that. So with that in mind, I checked
the material that I had not packed and found nothing. Then I though
I better check in the big heavy UYK-20 hardware manual that was already
packed away. I cut the tape and opened the box, took the hardware manual
out and started searching. Well after 10 minutes, I could not find a
thing. Finally I had to ask, “What’s a Pi Cost?” The
fellow then says to me, going from a stern serious look to a smile “Three
dollars and forty-nine cents”. Well talk about hook, line and
sinker, that was me.
Inthe old Univac training department, one
of the classes taught was the Computer Fundamentals Class. We had a
Study Guide for use in the class and it was pretty good. In those days
it covered things like Octal and Hex numbering systems and also things
like logic blocks, i.e. AND, OR, XOR logic functions. The course was
five days in length most of the time. We had a variety of students in
the class. The students ranged from people from the assembly line in
old plant 1 to technicians, new engineers and people who were in administration
positions. We had a computer for this called the Univac Digital Trainer.
It could even be hooked up to some kind of Flex Writer. The computer
could let you input programs from the panel. Dan Newton, who was the
manager at the time worked on this before becoming manager. I have no
idea of what became of this computer but it would be interesting to
see it again. This digital trainer would be an historic item to locate
[Maybe it’s in a warehouse someplace?] Another item that we had
was a 16mm sound movie that was an introduction to computer fundamentals.
I think it ran between 25 and 30 minutes. I have no idea as to what
became of that film.
Another item of interest
was another movie. This movie was produced by one of the major television
networks and it involved a former employee of Univac. In 1976, I was
conducting an AN/UYK-20 Programming Course for customers from Japan.
These customers represented the Japanese Navy and various companies
i.e. Toshiba, Mitsubishi, etc. The Japanese naval representative requested
that time be allotted to view this documentary film. The film was a
story about a P-38 Lightning plane that was shot down in New Guinea
during World War II. The plan crashed in the jungle and the pilot was
found by the local natives. He was on the verge of death but the local
population nursed him back to health. He even returned in later years
to thank them. He was an employee of Univac later on. Don Lovely
would remember this story as he was involved and I believe he knew the
pilot involved.
It is amazing to me that I am considered “an
old timer” to make a contribution to the history of the company.
Times have really changed. When I joined the company in 1959 I was part
of the Titan ICBM program. We used to attend meetings with other companies,
and we were always the youngest guys in the meeting. Funny thing, that
all changed by the time I retired in 1999.
I was fortunate to be part of the Titan Missile Project as part of Remington
Rand Univac. After some training in St. Paul I was assigned as Engineer
in Charge of one of the missile guidance systems at Cape Canaveral.
It was great to learn about missiles and guidance systems. The guys
from all the other companies were more than willing to teach you anything
you needed to know about their equipment, so you could do your job better.
As the years went by, companies who would some day be competitors were
not so willing to share information. As part of the ground guidance
team I had an opportunity to do something that not many people have
done. We were launching a special payload one day which included an
inflatable 100 ft. diameter aluminized balloon called ECHO. It was the
first communications satellite and you could bounce signals off of it.
The computer was supposed to send the signal to eject the payload but
the signal was not received by the missile. My job was to change the
computer controls from automatic to manual and then punch in the octal
code on the control console three times at five second intervals. Luckily
for me the signal was received and the payload was ejected and the balloon
was inflated. I received a joke award from our launch team called “The
Order of Digitis Extensionis”.
My
next assignment was to manage the installation and test of an operational
underground Titan Missile complex near Beale Air force Base in California.
Our team was requested to staff the Titan ground guidance system during
the Cuban Missile Crisis. We were all very relieved when the crisis
was ended and we were not required to fire the Titan missiles in response
to a Russian attack.
Upon return to St.
Paul I was assigned to work as a programmer and later as a manager of
the Automated Design Department. A programmer in those days worked in
machine code because compliers and high level languages were not yet
available. During this time of early 1963, Univac was far ahead of the
industry in the development of software for design automation. One of
the important software programs developed in this group was the wire
wrap router program. As computing speeds increased the designers required
the routing programs to take into consideration the shortest wire path
possible to transmit the digital signals.
My next assignment was to the Program Management office for the US Navy
S-3A anti submarine aircraft program. This was my first business relationship
with the Lockheed Martin Corporation. Little did I know that one day
I would become a Lockheed employee. I also worked as a Systems Engineering
manager in support of Avionics Programs. This work involved many challenging
new systems. Some of this work involved classified intelligence gathering
systems.
As a Systems Engineer I was also required to support the
Marketing Department on presentations to customers. It was at this time
that I also had to opportunity to participate in the generation of proposals
to the government customers. Writing proposals is a hard job but it
was great for building team spirit. Those were the days when we would
celebrate a win with a gathering of those involved on a project to enjoy
a barbeque and sweet corn picnic at the lake. Oh yes, there may have
been some beverages served also. After a few beverages had been consumed,
there would always be a round of singing which included the song ANEW
We Love You. This song was a parody to recognize all of the contracts
we had received over the years from the US Navy for hardware and software
produced in support of the Lockheed P-3-C aircraft.
In the later years of my career I mostly worked in Program Management
on a number of different programs. There are two programs that have
many memories associated with them. Those programs were the 6977 Communications
program for the Government of Israel and the Q-70 computer and display
program for the US Navy.
A part of the program
management team, I worked on the 6977 program. It was one of the first
international programs won by Univac. This program involved subcontracts
with companies from Israel, Italy, and several US companies. This program
was a learning program for our company. Doing business with foreign
companies has many challenges above and beyond the language issues.
The system got installed and as far as we know is still achieving all
of its objectives. This program did result in a two year international
arbitration of a contract dispute. Participating in the court proceedings
was a lesson in business practice. As I learned, you cannot avoid a
contract dispute in the way you write your business memos, but if you
take the time to ensure that the business memos truly say what you intend
to say, you can avoid multiple interpretations of your words at a later
time.
One of most memorable programs was the Q-70 program for the Navy.
This program was the first time that the US Navy decided to make use
of commercial off the shelf hardware (COTS). Until this point in time
all of the computer and display parts were ruggedized special design
and the software was written in a special Navy software language called
CMS-2. It was also true that for many years Univac had been the Navy
supplier of computers, and Hughes had been the supplier of the CRT displays
that were connected to the computers. Top management in St. Paul was
not at first willing to fund a proposal effort that would promise to
build a hardware and display system, since it was assumed that only
Hughes could win the competition. After several presentations to Univac
management, we were given permission to bid the Q-70 program, and we
were extremely happy when we won the competition. That program has been
a major business area for the company over the past several years.
In the last years of my career, I worked as a program manager on
several programs. I am glad to say that one of those programs was the
newest most modern class of submarines called the Virginia Class. This
program gave our company experience in some of the most technology challenging
communications systems available. The once Silent Service, has now become
an integral part of almost every military operation of our military
service.
Our company has changed a lot over the years, but one thing
has not changed, and that is the many good people who have contributed
to the company success.
REFLECTIONS ON MY CAREER WITH UNIVAC
After graduating from Mankato State College in 1958 with a degree in
Math and Physics, I was hired by Remington Rand Univac (RRU) as a Programmer.
I didn’t really know what a computer was so I was scheduled to
attend the infamous Dr. Brown’s digital computer logic class.
Besides learning about computer gates, it was my first exposure to the
binary and octal number systems. What an eye opening experience.
My first assignment was working on the Threat Evaluation & Weapon
Assignment (TEWA) module for the Service Test version of the Naval Tactical
Data System (NTDS). The strategy and mathematics for this “shoot-look-shoot”
philosophy was developed by Dr. Alex Radcliffe at the Johns Hopkins
University-Applied Physics Laboratory. It was a pioneering effort to
automate this function on board naval ships.
This was just one of many “firsts” developed for the three
Service Test ships during the early 1960s. Some of the others included
the first production solid state digital computer (AN/USQ-20), the real-time
operational software executive which allowed asynchronous operation
and automatic computing load balancing, automated intercept control
and automatic radar/target tracking. It was this latter capability,
developed by RRU, which led to the awarding of the first Air Traffic
Control contract and a long and successful association with the Federal
Aviation Agency (FAA). Through all of this, we emerged as the unofficial
system contactor for all subsequent NTDS variations and implementations.
The programming that we did was originally in absolute code, written
in octal numbers and punched in paper tape to be read into the computer.
This being very inefficient, led to our development of the R-3 Assembler
(which allowed relative addressing) and then the CS-1 Compiler which
allowed the programs to be written in English language logic statements.
This made it much easier to develop operational programs that would
exceed the 32K of 30 bit memory that was available in each computer.
After the original service test software was
ready in the early 60’s, Univac assisted the U.S. Navy in establishing
the Fleet Computer Programming Center, Pacific (FCPC, Pac)in San Diego.
Their responsibility evolved into that of developing the “official”
operational software since this was something that could not be done
by a private company since it involved devising and implementing naval
strategic and tactical doctrine. In essence, UNIVAC became the proof
of concept and prototype system developer and FCPC, Pac became the production
developer.
UNIVAC also pioneered the use of computers
to evaluate the actual installation and integration of NTDS shipboard
systems. This was accomplished with specific test software programs
developed for each piece of equipment, diagnostic programs for the computers,
Programmed Operational and Functional Appraisal (POFA) programs for
each piece of equipment interfacing with the computer and Integrated
Programmed Operational and Functional Appraisal (IPOFA) programs to
test the overall installation. This software turned out to be very instrumental
in the quality of system installation ultimately achieved by the shipyards.
During the late 1960’s, we were contracted
by the Navy to develop a specification for the process of software development
that became affectionately known as “SHIPS 0011,” an abbreviation
of the official specification number. This document addresses the entire
development process from developing the functional requirements, through
design specifications, programming and software testing. The specification
has evolved over time and became a Navy wide standard. This also led
to Univac developing the software quality specification that was used
Navy-wide for subsequent software procurements.
Because of the significant R&D that was being conducted by Univac,
the U.S. Navy created a digital computer combat system integration and
test center at Mare Island Naval Shipyard in Vallejo, Ca. It was at
this facility that the cutting edge digital technologies for digital
fire control and automatic radar control for detection and tracking
were proven to be viable prior to implementation in the fleet. The digital
closed loop control of the fire control radar, rather than the previously
accepted analog control, really opened the door to the eventual domination
of the digital computer in all of the combat system functions.
The Univac 1218 and 1219 18-bit computers became standard for the Naval
Weapons Systems Command for the digital replacement of the older analog
fire control computers for the Tartar, Terrier, and Talos missile systems.
Digital control of the AN/SPS-48 radar beam for detection and tracking
heralded a new concept of radar. T his eventually led to development
of the Aegis phased array radar system that is the mainstay in today’s
fleet.
The 1218 computer was also the heart of
the AN/SPN-42 Automatic Carrier Landing System that was developed by
Univac in conjunction with Bell Aero-Systems who had developed the original
analog system. This system was eventually deployed on all of the active
aircraft carriers.
The next major technology
breakthrough was in the early 1970s, the development of the AN/UYK-7
computer, the first computer with multi-processing capability. The first
operational implementation of this capability was in a two bay/dual
processor configuration on the SSN 688 (Los Angeles) class submarines.
Closely following was a four bay/triple processor configuration implemented
on the DLGN 38 class surface ships. The key advancement was the systems
tolerance to hardware failures. The system would automatically detect
the failure, isolate the failed component and adjust the computational
load until it could be removed and repaired.
This computer architecture rapidly became the standard for several offshoot
computer architectures that were used by the U.S. Marine Corps in their
tactical air control and command center shelters as well as the Apollo
program for their satellite tracking. The last major Mil-Spec computer
developments were the 16-bit AN/UYK-44 and 32-bit AN/UYK-43 computers.
Both of these production contracts were won by Univac in 1983 after
competitive development runoffs against IBM. These computers really
marked the end off the “bullet-proof” Mil-Spec computers,
for from that point on, the military’s hardware procurement emphasis
switched to utilizing commercial off-the-shelf components and open architecture
concepts as much as possible.
During the foregoing
time period, I was personally involved in these technology advancements
either from a Systems Engineering or Program Management standpoint since
I spent about equal amounts of time in both functional organizations.
Probably the most challenging assignment I had during my career was
first as Program Director for Eagan’s combat system software development
for the Canadian Patrol Frigates (CPF) and my subsequent transfer to
Montreal, Canada, from 1988 - 92 as the Program Director for the overall
program at Sperry/Unisys Paramax division. CPF was a major $2.4B system
development and management contact that required Sperry/Unisys to design,
develop, procure, install and test all of the electronics for the combat
system and machinery control systems for 12 patrol frigate class ships.
The contract started in 1983 and completed in 1996 with delivery of
the 12th ship. The first frigate was delivered to the Canadian Naval
Forces and commissioned in time for it to be deployed as the centerpiece
of Canada’s commitment to the first Gulf war coalition forces.
The CPF was significant in that it featured 33
computers networked on a SHINPADS data bus, working in a shared processing
environment that was completely fail-safe. The ASW and AAW modes of
operation were also capable of being controlled manually, semi-automatically
or fully automatically. This was the first warship that had these features
operationally implemented.
In 1986, Burroughs
purchased Sperry and Unisys emerged from behind the white curtain. Unfortunately,
this was the beginning of end of the legacy of UNIVAC as we all grew
to know and honor over the years - a legacy of leading edge technological
innovation and customer satisfaction. Fortunately, I had the pleasure
of working at UNIVAC during the “Glory Years,” starting
my career as a programmer in 1958 and retiring as Vice President, Engineering
in 1994. It was a great ride!
I joined UNIVAC in 1965 right out of College,
newly married, and ready to jump into this unknown new computer business
area. Fortunately, I had taken the only computer course available before
graduation; Fortran on an IBM 1620 using punch cards for the program
instructions and data.
After a few weeks of training
in St Paul on a programming language called CS-1, our little group of
8 new hires [including Tom Hanson, Tom Rougier, Lyle Olson, Dean Sandifer,
Roger Parker, et. al.] were transferred to Willow Grove PA to work on
a new project called ANEW. ANEW was the US Navy’s attempt to put
a digital computer on a Lockheed P-3-C to provide anti-submarine warfare
operational capabilities. Initially, we had a 32K computer with flight
testing being done out of Patuxent River MD.
In
1968, I followed the evolving ANEW project out to Burbank where Lockheed,
as prime, had the aircraft and a full laboratory mock-up for program
development and system checkout. It was the type of project where the
team was working 60-70 hrs a week for over a year; but the pay was good.
After working in front of the computer console for so long, one could
just look at the instruction execution light patterns and say if the
program was running normally. It still amazes me the extent to which
we programmers had to intimately know the computer architecture and
instruction execution details to develop programs successfully in those
days. Today’s normal SW engineer cannot fathom that HW/SW relationship.
Being a part of the Lockheed flight test crew, one had to endure 10-hr
long-range navigation test flights, MAD equipment alignment test flights
which also tested who had a steel stomach and tactical ASW fights flying
100-200 feet above the ocean. One flight experience sticks with me.
We were on a long inertial navigation accuracy test flight over the
Mojave Desert when the airplane hit an air pocket. I occasionally stood
behind the pilot looking out the cockpit to pass time. When the plane
hit the air pocket, I went up or the plane went down resulting in my
head jammed up into a metal part of the escape hatch. The blood was
flowing down my face and the flight was aborted to return quickly to
Burbank for some medical attention. What an exciting time for a guy
from Minnesota. It was a time of real job satisfaction.
P-3C [starting with ANEW] turned out to be one of the longest running
projects the company had, not only with the USN but with several other
world Navies.
My experience on the P-3C 1830A
computer brought me an offer to work on the German Fast Patrol Boat
Project, which used the 1830B (shipboard version) computer. In 1971,
my family and I transferred to the Netherlands where Signaal Co. (Prime
contractor) was responsible for systems and software development. The
development team, made up of Americans, Germans, French and Dutch, moved
to Wilhelmshaven, Germany to complete the effort. Some of the American
team included Lowell Benson, Bill Rogers, Dennis Christ, John Rachac,
and Jim Gannon. Being a multi-national project, we Americans were lucky
that both the work environment language and the social [party] language
was English. That made life relatively easy but, regrettably, did not
force me to learn German better than I did. My wife and I have maintained
relations with many of these early acquaintances to this day.
This started a 33 year long relationship with international business.
I joined the international Program Management group around 1977 thanks
to encouragement from Dennis Christ. Although my primary business area
was with Germany, over the years I managed contracts with Canada, UK,
France, Spain, Greece, NATO, Norway, and Italy. Visiting these customers
allowed me to travel throughout most of Europe during the best of times.
Besides the Fast Patrol Boat, other major German Projects included Frigate
122 (8 ships), Frigate 123 (4), Minehunter 343 (6). By the late ‘90s,
Europe and Germany adopted the strategy that, with the availability
of COTS equipment, system development could be done by their national
defense contractors allowing defense spending to remain more within
Europe. We lost the competitive Frigate 124 contract in 1998 mostly
because of that and that loss started the downward spiral for the Lockheed
Martin German business area. Since the time of the Fast Patrol Boat
project, St Paul always had a branch/marketing office in the Bonn area
handling the direct customer marketing interface and taking the prime
contract on behalf of St. Paul. Some of the notable Bonn office Managers
included Lee Dominick, Gary Holthusen, Gary Humfelt, Chuck Hammond,
Dennis Christ, and Manfred Wiese. Prior to Wiese taking the lead position,
St Paul always had an American heading up the Bonn office rotating every
2-4 years.
For years, John Byrne was the St Paul
international marketing man. John and I pursued many international opportunities
(business) together. Having Don Blattie normally as the international
contracts manager, made for many smooth running programs and Senior
Management expected international programs to provide good margins for
the Company. Not having exact figures, I would say the Japanese business
area, run by Bob Pagac, was the only business area that produced better
margins than Germany, over time. Over the years, I have had great bosses
including Dennis Christ, Bob Alexander, Bruce Grewenow, and Doug Schmitt.
In closing, it was a very good ride. I always
enjoyed going to work, which also means I enjoyed the people with whom
I worked.
I started to work with Remington Rand Univac (RRU)
in June 1960 after receiving an electrical engineering degree from South
Dakota State University. My first year at RRU was spent in the component
test lab in Plant 2 and writing hardware specifications. Working in
1960 at plant 2, which was a converted glider factory from WW II [and
the original home of ERA], was an experience. We covered our desks with
paper when leaving each day to keep the sparrows off the desk.
In 1961 I transferred into the Navy Systems Engineering department.
Approximately 25 of my 40 years with the company were focused on Navy
projects. It was an exciting and interesting time to be part of the
continued development of NTDS. When I started, NTDS had already been
introduced and tested on its first group of ships. In the early 60’s,
I developed software for equipment test programs, system interface tests,
and Radar Alignment and Designation Accuracy Tests (RADAT). These programs
were initially tested at the Mare Island Naval Shipyard test site. This
was a great time to be an engineer and software developer. The projects
at Mare Island were focused on doing things with digital computers that
had not been done before - automating command and control functions,
automating radar processing, and establishing digital interfaces between
NTDS, radars and Fire Control Systems. Once the RADAT software was ready,
I took the test aboard all of the ships in the CG26/28 class (CG26-35)
and three aircraft carriers to test the alignment of all of the search
radars with the fire control radars.
I’ll
never forget my first trip at sea on board CG 26, the USS Belknap. Before
the ship sailed I was playing around with the test software at a display
console not realizing that my balltab (cursor) was directly connected
to the massive multi-ton fire control radar. As I moved the symbol from
one side of the display screen to the other side (i. e., violent sudden
changes in bearing) there would be a whooshing sound and the ship would
vibrate. After a minute or two a young fellow came up to me in a hurry
and said “Whatever you are doing stop!!!” Apparently my
designations through the system were being accepted directly with no
damping or smoothing. The necessary controls were put into the system
so the problem went away.
As the ship sailed
from the pier at the Bath Iron Works in Bath Maine, I was inhaling tomato
goulash in the officer’s dining room not realizing that once out
on the ocean it would be a bit wavy. My first experience with sea sickness
was unforgettable. When the ship returned three days later my first
task on landing at the pier, after putting my feet on solid ground,
was to call CDR Boslaugh (When Computers Went To Sea) and Jim Mountain
for whom I worked at the time. It was a new experience for them to send
a young programmer out to sea so they were interested in a report. The
experience gained from these trips at sea gave me a great appreciation
for the magnitude and complexity of the electronic systems on board
ship.
In the late 60’s I left software test
development and focused on system studies and hardware interface development.
One of my projects was to manage studies and prototype development for
the NTDS serial Input/Output (I/O) interface. It seems a bit unusual
now, but at the time sending digital information over one wire was considered
to be heresy by some people. Cmdr Drenkard was the Navy project officer
supporting the studies and held fast to pushing for a serial I/O interface
over one coaxial cable wire. During the development of the serial interface
I read and adopted some of the interface philosophy defined by Dave
Lundstrom (A Few Good Men from Univac) who left behind a number of I/O
white papers when he left the company for CDC. Dave was considered to
be the I/O expert for the development of the original NTDS interfaces.
The result of these studies and prototype efforts resulted in the specification
of the NTDS Serial Interface {Editor's note: This
serial interface became MIL-STD-1397 Type D, preceding the later Low
Level Serial.}
Before leaving the
1960’s I would like to say something about the way work was performed.
The 60’s can be characterized as a time “before PCs" and “before
copy machines”. Our secretaries would type all of our documents
usually with carbon paper. If we wanted something copied in Plant 5
we would go to the ozalid room for copies. In the early 60’s I
would be debugging my software programs late at night in plant 5. All
direct computer work was performed at the computer front panel in binary.
Software would be compiled on the target machine and punched on paper
tape. If the punch would erroneously punch the wrong holes, the whole
process would be repeated. Work energy was high both in St. Paul and
at Mare Island. After work hours in St. Paul, there were many intramural
sports. I particularly enjoyed fast pitch softball (slow pitch had not
been introduced yet) with Hank Zelenka as our pitcher. Everybody worked
hard and played hard. Work hours at the Mare Island Naval Shipyard were
scheduled 24 hours per day so it was not unusual to be assigned work
time at night. I remember getting a speeding ticket late one night for
exceeding the 10-mile per hour limit.
I worked
with the Navy to define the requirements for the Data Exchange Auxiliary
Console (DEAC) during 1969 and then carried the project through the
pre-proposal and proposal stages as the proposal manager. The DEAC became
the primary auxiliary interface for keyboard/printer, paper tape reader/punch
and magnetic tape interface during the 70’s and 80’s.
The Junior Participating Tactical Data System (JPTDS) system development
started in the early 70’s. I was the project engineer for the
JPTDS as well as some related hardware system developments. The JPTDS
was ultimately installed on the DDG-2 class of ships. Part of the JPTDS
contract required the installation of a small JPTDS system in a forty-foot
trailer that could be moved to various locations. Once completed the
trailer system was located at Mare Island where it supported testing.
The system installed in the trailer used the NTDS Serial Interface for
the first time. One of the Magnetic Tape Transport’s (MTT’s)
was removed from the DEAC and replaced with a small analog to digital
converter [Integrated Circuit KCMX] to enable the input of ship motion
synchro data. The trailer also contained either the first or second
UYK-7 built so it became a test bed for new hardware concepts. The JPTDS
contract work was initially performed under the overall direction of
CMDR Campbell followed by CMDR Crandall. During the development of JPTDS
the navy was promoting the system and the UYK-7 to foreign navies. On
a number of occasions I would accompany the Navy and company marketing
representatives on international trips to give presentations on the
system.
A large variety of system studies and
proposals were generated during the 70’s, dealing with the application
of digital computers to shipboard systems. One of the study efforts
resulted in the definition and implementation of the Shipboard Integrated
and Processing System Serial Data Bus (SHINPADS SDB). The study effort
for the SDB started in 1976. Prior to 1976, we had been actively involved
in distributed processing IR&D studies. Gene McCarthy from the Marketing
department had established a relationship with the Canadian Navy and
was instrumental in winning a study contract for defining the SHINPADS
SDB. Gene setup a good working relationship between the Canadian Navy’s
CMDR Carruthers and their engineering. CMDR Carruthers was a primary
proponent of developing a distributed Naval Combat System architecture
having a large number of computers interconnected with a serial data
bus. CMDR Carruthers wanted to stay close with our engineering activity
directed at the definition and development of the SDB since it was key
to the ultimate success of SHINPADS. As a result, CDR Carruthers would
call frequently to discuss distributed system philosophy and the status
of the SDB development.
The SDB proceeded from
definition, prototype development, testing and many demonstrations to
a final specification for the interface. These efforts were spread over
a time period of about 3 years with many presentations and meetings
to discuss the feasibility of implementing a distributed processing
system with the SDB. A description of SHINPADS and the SDB was presented
at the 1979 American Society of Naval Engineers (ASNE) annual symposium
and published in the April 1979 Naval Engineers Journal. [1. Carruthers,

The 80’s were spent in various management positions coordinating
system studies, proposal development, IR&D projects. I spent a few
years working on a Master of Science in Software Engineering from the
University of St. Thomas-finally earning the degree in 1988.
For three years in the early 90’s, I was the Project Engineer
on a classified project located in Camarillo, California (two plus years)
and then back in Minnesota for the final few months.
After returning from California I took a temporary assignment with the
UNISYS World Trade Division where I was the Site Manager in Vienna,
Austria for a few months and readied the project for transfer to Prague
and then was the Development Manager in Prague, Czech Republic on a
commercial banking system development. The total length of the European
assignment was 14 months. One of the chief challenges of this project
was directing the work of over 30 people from 7 different countries
with all but two of the people being sub-contract programmers. One of
the programmers on the project was from Slovakia and did not speak English.
Another programmer was from Russia and lost his visa suddenly in Prague
and was not allowed to stay in the country. I missed the services one
would normally expect in a large company environment.
After returning from Europe I worked for Larry Huff where I initially
managed new technology studies for the UYQ-70 Display System and then
managed a Communications business development group and Communications
IR&D project until I retired in 2000.
My focus
over 40 years with the same company, starting with Remington Rand Univac
and ending with Lockheed Martin with several company name changes in
between, was on software development, system engineering, marketing
support, and engineering management. Changes to the work environment
before PCs and after the introduction of PCs were dramatic as were changes
in computer technology. On many projects, we felt we were working with
our customer as a team to accomplish our customer’s mission of
introducing digital systems. I particularly enjoyed the people I worked
with.
In June of 1977, I was hired as a young man of 19 into Sperry Univac – Navy Systems Customer Service Engineering group lead by Bob Hedlund. After 4 weeks of maintenance training of various NAVY equipment (AN/UYK-7, UYK-20, OJ-174, 1532, and 1540 to name a few), I started my career are a field engineer.
My first company trip was with John Bly aboard the USS Ajax to refurbish the UYK-5 system (1218, 1540, CRIPI, and HSP). Little did I know at the time that I would eventually visit every destroyer, cruiser, and aircraft carrier through my future field engineering years supporting all type of UYKs and peripherals we provided to the NAVY. Along with ship visits I also had several site deployments including a three-year stint in Pascagoula Mississippi Ingalls shipbuilding supporting the DD-993 class and the last of the Spruance class build and a 1-year effort supporting the S3A aircraft flight-line in Burbank, CA.
In 1994 through 1996 I transferred to the Air Traffic Management group in Eagan where I led the deployment of the Common ARTS systems in Dallas TX and Denver CO and supported the STARS pursuit.
Back to Field Engineering in support of our new product, the Q-70. Along with Larry Cude, I was the original field engineer in support of Q-70 deployment. I spent numerous hrs between the factory and sites assuring our product would integrate with the various platforms. This was the first effort in integrating COTS into shipboard fire control and weapons systems. I supported the tiger teams on the USS Hue City and USS Vicksburg in the integration of Q-70 into the AEGIS Weapons System as well as the supporting integration into the SQQ-89 and NAVY avionics platforms.
In June 2009, I transferred to the Air Traffic Group as the Operations Manager supporting all the IS&GS Lockheed Martin activities in Eagan. In December 2012, we moved from 3333 Pilot Knob to our new site at 1303 Corp Center Drive. In August 2015, Lockheed Martin divested our organization. Thus, on August 16, 2016 I became an employee of Leidos Corporation’s. Air Traffic group. By Steve Koltes.
The Nov. 2006 issue of the VIP Club Newsletter had an article about you working on compiling a catalog of patents. I am listed as an inventor or co-inventor on 9 US patents. The patent numbers and the titles are listed below. The two with the smallest numbers are probably from before 1975. The US Dept. of Commerce Patent and Trademark Office issued a Secrecy Order on one of the patents listed below when it was in the application process. I mention it mainly as a point of interest for your information as not many people are aware of the them. It probably isn't appropriate to include such info with the history anyway.
I worked for Univac/Unisys from June 1956 to March 1989, when there was a voluntary retirement offer. I worked mostly on the 1100 series (latter models were called the 2200 series) starting with the Univac Scientific Model 1103A. They were all for the commercial market although many were used for nation defense and security purposes. Starting in 1967 I worked as a logic designer at Roseville.
Names of some people that probably have patents and aren't members of the VIP are listed below:
Thank you for your work in compiling this history.
A Career of Design & Drafting of Printed Circuit Boards and Drawings by Bob Langer
Where would a computer company be without a key ingredient
for its success such as the printed circuit board (PCB)? Of course it
would not exist. The design of the PCB artwork patterns, the supporting
documentation and the tooling used to manufacture and assemble PCB’s
must be cost effective, very accurate and with fast turnaround. I was
hired in1957 by Remington Rand Univac and retired in 2001 with the same
company now called Lockheed Martin. I was in the same Design and Drafting
organization for my entire career of nearly 44 years. This includes
two years of military leave in the U.S. Navy aboard the very popular
tourist attraction the U.S.S. Intrepid, a WWII aircraft carrier, which
currently rests in a New York City harbor as a museum. It attracts over
750,000 visitors annually.
My educational background
was one year at the University of Wisconsin River Falls in a pre-engineering
course prior to employment and during employment I received a Certificate
of Completion in Electronics after 3 years of night classes at St Paul
Vo-Tech.
My career started as a draftsman working
primarily with the design of PCB artwork patterns from circuit sketches
designed by electrical engineers. In the early days we used black masking
tape 1/8” wide and 3/8” round donuts or pads to create the
circuit pattern for the artwork at a scale of 4:1 which would be photo
reduced to 1:1 by the factory. That artwork photo tooling was used to
etch the circuit pattern on copper clad board material. I would estimate
hundreds of artwork patterns for many projects were developed by our
PC Design Group for fabrication and assembly by our own factory during
my career.
A very significant advance in the
development of PCB artwork patterns came with the new age of drafting
automation called Computer Aided Design (CAD.) In the 1970’s Earl
Vraa’s Software Group developed the software capability for drafting
to input the electrical engineer’s schematic sketch into our company
mainframe computers to automatically route circuit lines and generate
artwork patterns for multilayer PCB’s. It also provided associated
schematic and related drawings to fabricate and assemble circuit cards.
I always felt this software provided our company a very competitive
edge giving us the advantage over other computer companies to win major
defense contracts such as AN/UYK-43 and other major projects. At that
time I was responsible for the PC Design Group that did all the artwork
designs and documentation for our Defense Systems organization. I would
venture to say the peak workload for our group came in the1980’s
during the design and development of projects for AN/UYK-43 and AN/UYK-44
computers.
This was also the startup of integrated
circuit design and development within the PC Design Group. I was responsible
for 55 people in this new PC/IC Design Group including the photo lab
area which produced the glass plate tooling and provided coordination
with manufacturing. The IC Design portion of the group separated to
become part of the new semiconductor facility during this period. In
the1990’s the PC Design Group started using personal computers
with proven vendor supplied PC design software required for the very
complex PC designs. These new designs using complex integrated circuits
significantly reduced the overall quantities of circuit cards needed
for a project causing a reduction in drafting personnel, the closing
of our manufacturing facility and was my time to retire.
Overall I had a real interesting career experience going from a manual
operation with a large number of great hard working people to a totally
automated group requiring only a few highly skilled PC Designers using
outside vendors for manufacture. I still meet monthly for lunch discussions
with the retired designers and engineers and enjoy playing golf with
them quite regularly. Bob Langer
I graduated from Gustavus Adolphus College in
1952 with a BS degree in Mathematics and Physics. That first summer
out of school I was a counselor at a summer camp for boys. After that
I was notified that I was to be drafted into the army. The Korean War
was in its last days, so I chose to enlist in the US Air Force.
Because of my education they sent me from basic training to Wright Patterson
Air Force base to support a new US Air Force facility for computers.
At the beginning, my class received training on the IBM CPC equipment
(Card Punch Calculators). After the training - we had a choice to work
with IBM CPC equipment, analog equipment, or Digital equipment. I selected
to work with the OARAC (Office of Air Research Automatic Computer) digital
computer group.
My first job was to maintain the OARAC computer,
a 2*421 ten digit with sign electron tube design with drum storage that
had fixed heads. The OARAC computer was a copy of the Harvard Mark 4
computer built by GE. Early on, Phil Desilets of Univac instructed
us on digital computer techniques. I was later sent for maintenance
training on the ERA 1103 computer as the Air Force was planning to replace
the IBM large scale digital computer with the 1103. The 1103 training
started with CRT storage tube memory and ended with a core memory system.
While in 1103 training, I watched the ERA sign being changed to Remington
Rand on the entrance building to plant 2. When the 1103 arrived from
UNIVAC the Air Force chose to have it with a maintenance contract.
After the 1103 was in use, a fellow engineer
and I were planning to build for the Air Force an 1103-like computer
using repackaged OARAC components. My associate was to do the logic
design and I the circuits and packaging. We worked on the design for
a few weeks and than were stopped by management: we were told that the
US Air Force does not design and build computers. A private company,
SRL, took over the design and also the maintenance of the OARAC computer.
I was selected for training and to accept a core
memory storage system from Telemeter Magnetic for the OARAC computer.
The design was originally with the use of electron tubes but the Vietnam
conflict had stopped work on it. After the war, the memory was built
using transistor logic. During the later part of my time with the US
Air Force we were visited by Noel Stone, chief engineer of UNIVAC, for
a couple of weeks. We learned about the design of the Athena computer,
among other things. At the end of my time with the US Air Force, I managed
a contract that we had with Harvard University using the MARK I computer
to create ballistic artillery tables. I also handled a number of other
small contracts in research related to computers.
I came to work at UNIVAC on 01 February 1960 in time to be assigned
to the NTDS AN/USQ-20 computer design. My first job was to document
the design as it came out from the logic designers. I would check the
validity of some of their designs and our group of technicians would
tabulate the results. Jens Peterson and I were than asked to prepare
the test procedure for acceptance of serial 13 computer, the first computer
to be produced in our contract with the US Navy. At the completion of
these early tasks, I was asked by Finley McCloud to take over the engineering
support to manufacturing and final test for these first set of computers.
Of interest to me during this assignment were a couple of questions
which were asked by Arnie Hendrickson and Roy Hegler.
Arnie wanted to know when serial 13 would be ready for acceptance by
the US Navy; my response was 2 weeks after I receive it back from manufacturing.
Little did I know that he started the clock and
one week later I was told the US Navy would be in Monday for acceptance.
That meant the weekend was a scramble with 24 hour days. When the Navy
walked in we pressed the run button for the first time that morning
and the computer stopped with an error, we pressed the run button a
second time and the computer ran as it should and we told the UNIVAC
acceptance team that it was theirs. The acceptance went well that day
but it came up with a memory plane failure and the memory group showed
that they could replace the plane within the 3 hours allowed to maintain
the computer. Later that day during the endurance run, the computer
stopped with the same error we had had that morning. The failure turned
out to be a logic error in the I/O. The Navy went away satisfied with
the day. A short time later Roy Hegler asked when would serial 13 be
ready to ship, again I said in 2 weeks, he went away laughing and saying
no way. We did come close to shipping serial 13 in two weeks after his
asking. The success of the NTDS computer design and build within an
8 month period can only be attributed to the diligent work of the engineering
and the manufacturing teams.
For a short time
I was assigned to a supervisory position in the peripheral equipment
engineering group but, I felt fully out of place with the many highly
qualified peripheral engineers. A position became open as equipment
engineer on the Ascension Island Real Time Radar Data Handling System
for the Atlantic Missile Range program, and this fit me much better.
We put together a group of peripheral equipments around the AN/USQ-20A,
this also was the first application of the control console above the
access doors and we painted the equipment Air Force green.
After delivery of the system to Ascension Island it did not seem to
be going together very fast so the lead project people at UNIVAC met
and it was determined that someone needed to go to the Island to find
out why: I was selected. First, RCA was in charge of facilities and
we had just beaten them out of this contract. No help would be received
from them so our people had to remove all the old equipment in a room
in the FPS-16 radar building before we could install our equipment.
Secondly, the radar system was not as we had
designed the software for and we had to reprogram. Lessons learned:
visit a site at the beginning of a program and get it right the first
time. During my nearly two month stay on the Island, I learned how to
pick locks so we could work more than one shift as we were not issued
a key to the site. I also had to repair equipment without spares and
be available to counsil my people who had been on the Island too long,
as well as to be firm with them. We needed them all to be fully functional.
The nights sure are dark on an Island in the
middle of an ocean when you have to walk back from a radar site to your
housing quarters. I made a decision that the UNIVAC people would leave
the Island on December 8th for Christmas. Prior to leaving, a couple
of engineers flew in from UNIVAC with a new compile of the software.
A few days later after the RCA people on the Island had lost the nose
cone using their manual techniques. We were told that our system would
be used the next night and true to the diligent work of our system engineers
and software programmers on site the FPS-16 radar was put on the nose
cone as it came into the atmosphere and followed it to splash down.
Victory!
While the lead designers were assigned
to develop the CP-642B, the next task I was asked to lead was the design
of the 1218 computer - three young men did the logic design: John Lee
(later of Lee Data), Leroy Olson, and Don Mager. The mechanical design
was to use a common packaging developed for future equipment by the
mechanical engineers under the leadership of W.W. Hemer. The mechanical
engineer that I worked with on the 1218 was Jim Warwick. The 1218 program
was a little rough for awhile at the start as we had many component
problems, such as, indicator lights that seem to set the computer off
running with no apparent reason. During the 1218 life I was able to
have installed a number of modifications that were given to me by my
engineers; this proved to give this computer a great boost in reliability
and at the end it was the first computer to go thru all environmental
tests without a glitch.
For about seven years
I functioned with increasing levels of responsibility from project supervisor
to Manager of Computer Design with responsibilities for design and development
of equipment for marine, transportation, and international systems.
These duties included design of equipment used in the ARTS III program,
1218, 1224, 1219, 1230, M1218, Punch Control Unit (Crispi), 1224 [Project
Tuggle], APOLLO display system, 1236, M555/MASU, 1230 MTC (1530), Mark
152 [Talos launcher computer], CP-901 [type 1830A], 1830B computers
and accountability for Product Control and Engineering.
After we completed the 1530 design in a 8 month period, from start to
delivery, Red Phillips told me, "you have had an easy one now: I want
you to take over the CP-901 program with all its environmental and documentation
problems." This project led to the development of the Fast Patrol Boat
1830B computer system for the German Navy. We put a splash proof suit
on the 1830B and had the memory system modified to make it more easily
manufactured. I was than asked to transfer to MSD Operations in Germany
as site Supervisor and Technical Manager for the UNIVAC portion of the
German S143 program in Hengelo, Netherlands. After 6 months on site
we were transferred to MSD Operations in Bad Gödesberg Germany where
I was given the responsibilities as Director of European Defense Operations.
I held this position for four years.
In August
of 1975 I returned to Univac DSD in St Paul MN. During these last years
at UNIVAC/Unisys I worked on technical and proposal support of European
programs, engineering support of the S-143 program, integrated logistics
support to the F-122, S-143, S-143A and TRMS programs. I also provided
technical and proposal support to Australian programs including a two
month stay in Australia.
I was system implementation
and test manager of the 6977 test bed operation and was prepared to
implement the system design in-country. I supported many domestic and
foreign country proposals through out these last years. The Turkish
Navy Control and Reporting Center (TNCRC) was my last real design project
with responsibility for selecting and developing the installation design
for the equipment in two interconnected S-280C/G shelters. The equipment
shelter housed the power, communications, and interface equipment while
the operations shelter housed the processing equipment, operator consoles,
and operator interface equipment.
On 31 December
1991, after 38 years in the computer business, I retired from Unisys
to a country farm environment - learning new skills, working with nature,
doing family genealogy, and living my Finnish heritage.
Graduating in June 1961 from Iowa State with a
BS EE, I accepted a job to test and checkout 1107, 490, and Univac III
memories. I wrote the final assembly and test procedures for the 1107
and Univac III memories.
In 1964 I become part
of Navy Systems located in plant #1. After several years of writing
POFA test programs for military peripherals, Mike Kokesh and I developed
radar alignment tests (RAT) for the DEs 1047/49 [Voge/Koelsch]
and the CVS-18 carrier, Wasp. I modified the RAT program for the German
Navy DDG-28 class and went to sea four times in total on these three
German destroyers [D-185/6/7 Luetjens/Moelders/Rommel].
Larry Duder later modified the RAT for the Japanese Navy DDG-168/9 ships
[Tachikaze/Asakaze]. In March 1970 I received
my MS EE from the University of Minnesota.
My
next major assignment in 1972 was in charge of writing operational program
specifications for the Japanese Navy (JN) DDG-168. The software was
then developed and installed by TSD Valencia. The success of this effort
resulted in the Univac development of three more major Combat Direction
Systems (CDS) for JN ship classes from 1976 to 1984. I was proposal
manager and technical engineer supporting Marketing for these efforts.
From 1974 to 1985 I was assigned to International
Marketing to manage numerous proposals especially for Far East bids
to Japan, Korea, and Taiwan. This required many trips (~15) to Asian
countries to meet with Navy officers of these countries. Mel Javinsky,
Jerry Polk, and I spent the month of July 1980 inspecting Korean Navy
(ROKN) Command Centers at Seoul, Inchon, Chin Hae, and Pusan as part
of a Naval C & C funded study. Marketing managers were usually Jim
LaCroix, Y. Tomagawa, Taki Saito, and Tom Knops. In 1977 Univac employed
retired Vice Admiral John T. Hayward as a Republic of China (Taiwan)
marketing consultant. Adm. Hayward commanded the first nuclear powered
task force in naval history and was named president of the Naval War
College in Newport, RI in 1966, and remained there until his retirement
from the Navy. For several years he asked me to call him at home after
each Taiwan trip to brief him on Taiwan programs and the Captains and
Admirals that we had met with.
During this same
period I represented Univac at a number of meetings in Germany that
initiated German Navy projects. The German Navy had requested that only
company representatives attend who were fluent in German. Three of these
trips to Germany were made with Dennis Christ then Navy Program Director.
Over the years I translated numerous German Navy articles.
From 1985 to 1989 I worked on the Canadian Patrol Frigate (CPF), first
coordinating the St. Paul efforts for the detailed presentations to
the Canadian Navy for each of the major ship subsystems. My able assistant
was Bill Lynch. Sperry System Management, Great Neck, NY was the combat
system prime and Sperry St. Paul the major software supplier. For two
years I worked with Mark Garber developing the CPF Combat System User
Manual. In 1989 I was assigned to work at PARAMAX, Montreal for environmental
qualification of the CPF Integrated Machinery Control System (IMCS).
In late 1989 I supported marketing support for
the German Navy F-123 frigate with several trips to Germany. For the
first eight months of 1990 I was assigned to work at the Blohm and Voss
shipyard in Hamburg, Germany to help define the simulation system concept
for the Wilhelmshaven test site and the overall planned combat system
acceptance test schedule. Project engineer for the F-123 [Brandenberg
class - four ships] contract was John Dagon. In the Summer of
1992 I was assigned for 10 weeks to Bremen, Germany to review and assist
Krupp Atlas in the review of ship test documentation. All documentation
was in German.
In the Summer of 1996 after having
been laid off from Unisys for 2 1/2 years, I was rehired and assigned
as a test engineer working for test supervisor Tom Grenzinski and project
engineer Dennis Abbott to develop test and acceptance procedures for
the Royal Australian Air Force (RAAF) P-3C avionics system software.
My test procedures were for the display module and maximum system loading.
My final assignment in 1999 was to develop test
and acceptance procedures for the Short Term Conflict Alert (STCA) contract,
an air traffic control warning system for the Deutsche Flugsicherung
(DFS), the German FAA. The system was developed under the direction
of project engineer Joe Fellerer and lead software engineer Larry Scherber.
I performed these acceptance procedures seven times in Germany at the
Munich, Frankfurt, and Bremen regional control centers. My last certification
test was September 2001.
Richard F. Lundgren was an employee of UNIVAC/Sperry/Unisys/LMCO from 1967 to 2004. He was a computer and peripheral hardware maintenance instructor for most of his career.
