Legacy Exhibits

When the Legacy Committee began in 2005, one of our long term objectives was to find a permanent place to display our artifact collection.  We found it in 2011 when the Dakota County Historical Society (DCHS) agreed to accept donation of our artifacts and to establish a permanent exhibit at the Lawshe Memorial Museum in S St. Paul.  Thanks to VIP Club member emeriti Bernie Jansen and Millie Gignac who worked with then DCHS Director, Chad Roberts to get the 'ball rolling'.  Bernie and Millie were also DCHS trustees thus knew the people who could make the decisions. The VIP Board and Legacy Committee are forever grateful for the hundreds of hours which John Westergren put in to arrange for the transfer of the artifacts collected over 7 years from retirees and stored at the Eagan, LMCO facility between 2007 and 2012.

There were already two small 'artifact' display sites in Minnesota; at the UNISYS, Roseville facility in Eagan and at the Minnesota Historical Society's St. Paul Museum.  Neither was positioned to become a permanent exhibit location. Our archive advisor, the Charles Babbage Institute Director, only accepts two dimensional objects thus by policy couldn't do permanent hardware displays.

We know of a other museums, listed at the right and detailed in section 6,  which have one or two items displayed. We  indeed appreciate their preservations of our Legacy.

1.0 Lawshe Memorial Museum - S St Paul, MN

The Realization of a Dream article relates the history of the beginning of the exhibit(s) at this museum.  With over 1,000 artifacts this may be the worlds largest collection of defense industry hardware artifacts that range from individual Printed Cards to operator workstations to full sized processors. .

The Dakota County Historical Society had a grant from the state of Minnesota to solicit exhibit ideas and down select from those ideas to develop specific history poster board topics. Keith Myhre developed the original listing of history topics in section 3.1, ..., 3.5 below. Over a dozen exhibit posters were developed under this grant during 2014/15. Within the listing are links to those poster pdf files or to pages on this web site which provide expanded topic details or links to this web site's legacy stories.

An upstairs multi-purpose room in the room has a suite of five workstations where Club volunteers are working to catalogue some ~20,000 photos, slides, and films. There is also a small collection of documents and books available for researchers to peruse during business hours.

2.5 Products/Systems/Applications/Departments

3.0 Unisys, Eagan Minnesota

Sperry-UNIVAC in Roseville had an earlier sense of history in the 80s, thus began to illustrate computer technologies with a series of wall mounted shadow box displays.  Harry Smuda [Management] and Dick Petschauer [Engineering] led the creation of these shadowboxes.  After the Burroughs buyout of Sperry in 1986; the resulting UNISYS Company kept the displays - adding to them as new commercial computer systems were developed in the 90s.  During the summer of 2017, UNISYS management moved the shadowboxes from Roseville to Eagan the summer to preserve our history. 

Unisys Roseville was in operation 1964 to 2017. Unisys Eagan opened in 1987, consolidating several Sperry and Burroughs Twin Cities facilities in this facility on Pilot Knob Road.  Our thanks to retirees LeRoy Larson and Tom Curie who volunteered their time to refurbish the wood frames of the shadowboxes before they were mounted on the walls of the Eagan facility.

We celebrated the transfer of the Shadowboxes with an Open House and Legacy display on September 13, 2017 - Through the Ages.  The first box in the picture at the left includes a pluggable vacuum tube chassis from the ERA/UNIVAC 1103. Mike Svendsen and Lowell Benson have documented the details of these boxes. The first has the 1953 1103 computer components, including a vacuum tube logic module.  There is also one of these modules available for closer inspection in storage at the Lawshe Museum.

A second set of shadowboxes displays the systems developed during the 80s; focusing on some of the micro-technologies employed and technology from our Semi-Conductor facility in Eagan - Click here for detail pictures and descriptions of these seven shadowboxes [FY-79 through FY-85.]  When Burroughs bought Sperry to form UNISYS, management decided to close the Eagan Semi-Conductor facility thus the FY micro-technology developments and shadowbox technologies ended.   

4.0 Charles Babbage Institute, Minneapolis Minnesota

Although CBI is the major repository of our collected documents [we've sent them over 1,000], a photo on the wall of their main office [left] is a drum memory collage showing various steps of the drum manufacturing as well as various sizes of drums. The smallest was an airborne 2052 processor memory - being held in the engineer's hands. This collage is about 4' x 7', originally hanging on the office wall of Bill Norris' ERA/UNIVAC St Paul office.

When Mr. Norris left UNIVAC with others to found Control Data Corporation; plant maintenance cleaned out his office - giving the collage to Don Weidenbach, the young engineer shown kneeling in the picture.

After being in Don's home office for over 50-years, Don donated the collage [right] to the Charles Babbage Institute - Dr. Tom Misa, Director of CBI [2006-17], is shown accepting the collage on behalf of CBI. An interesting part of our legacy is that the CBI Director holds the Engineering Research Associates Land Grant Chair for the History of Technology at the University's College of Science and Engineering.

The Babbage Institute is located at 222 21st Ave S #221, Minneapolis, MN 55455. For more information, see

5.0 Minnesota Historical Society Museum, St. Paul Minnesota Prototype Drum

This facility has the original drum memory prototype [left], the great grandfather of today's computer hard drives.  In 2006, Dick Lundgren and Don Weidenbach met with then archivist Matt Anderson, and convinced Matt to make this drum prototype a part of the Greatest Generation exhibit.  Another part of that exhibit was the story of an early lady programmer, Jane Pejsa.

Although not confirmed, MHSM may have an operator/maintenance console/panel from a UNIVAC II - used in the ERA/UNIVAC plant in the early 50's as St. Paul engineers developed a the UNIVAC II core memory for the Blue Bell headquarters.

This museum is located at 345 W. Kellogg Blvd. St. Paul, MN 55102.

6.0 Museums Away from Minnesota

Our traveling retirees have seen UNIVAC/Sperry/UNISYS 'relics' in several other cities including a Dulles Airport extension of the Smithsonian. The facilities listed hereunder contain one or more hardware artifacts.

6.1 Computer History Museum

The world's largest history museum for the preservation and presentation of artifacts and stories of the Information Age located in the heart of Silicon Valley; Computer History Museum. It is located at 1401 N. Shoreline Blvd Mountain View, CA 94043. They have a number of artifacts from Univac including a 642B computer as part of their NTDS exhibit.

The Computer History Museum offers a wide variety of information, exhibits, research and a rich library of multimedia content garnered from some of the most influential people of the computing era. Take some time to dig deeper into computing history and the one-of-a-kind information available here. There's something for everybody, they have an extensive set of history videos, .

6.2 USS Midway Museum

The USS Midway Museum is located at 910 North Harbor Drive, San Diego, California, 92101, alongside the Navy Pier;

From Craig Neudahl: While on board the Midway Museum tour this month I saw some familiar things from my past. I hired in at plant 1 to build the UYK-20's.

   The S-3A Viking computer [AN/AYK-10, Sperry type 1832] was a co-project on the same test floor.

6.3 American Computer and Robotics Museum (ACRM)

This museum is located in Bozeman, MT. Their website is
They acquired an UNIVAC 418-II that was used in Houston during the Apollo Moon Missions at the Mission Control Center.  That UNIVAC computer was implemented along with the three UNIVAC 493 computers for the reception of the telemetry data prior to it being passed on to the IBM 360s on the other side of the room. In operation since 1990, they advertize themsilves as: "The American Computer & robotics Museum is the oldest continually operating museum of its kind in the world.

Their page has a scrolling set of pictures showing many of their artifacts, intresting to me personally as a 'wanna be' cryptoligist is that they have a WWII three rotor Enigma machine.


6.4 Vintage Computer Federation (See for details.)

Vintage Computer Federation –We were Mid-Atlantic Retro Computer Hobbyists (MARCH) from 2004-2015. That group was just a computer club. In 2015, we disbanded and reformed as a national non-profit, the Vintage Computer Federation (VCF), which obtained 501(c)3 status. VCF then formed a Mid-Atlantic chapter to replace the old hobbyists group. The VCF local chapter operates as before, however the national organization is doing far more activities. For example, we acquired the Vintage Computer Festival West (to supplement our existing Vintage Computer Festival East), and we also acquired Vintage Computer Forum which is our hobby's largest discussion site. We have many other goals for 2017 and beyond -- incubate new chapters, restore more systems, and so on.

Our museum group in NJ has a Univac 1219B - This suite of equipment came from Johns Hopkins University Applied Physics Laboratory, where it was used to develop software for the Terrier Surface Missile System.

  • We recently started doing some real work on it. Specifically, we made progress on a paper tape I/O console. Next, we're having power circuits installed to let us run the CPU and tape drive via its motor generator.
  • We also want to build custom forklift pallets, do some cosmetic restoration, and build a modern educational exhibit for the systems.

To accomplish this (and other projects related to our organization overall), we're hoping to raise $5,000 -- one dollar for each calculation per second performed by the original ENIAC. The fundraising page is and, of course, it's tax-deductible. Thank you,
Evan Koblentz; Director, Vintage Computer Federation, a 501(c)3 educational non-profit

The museum is part of the Info-Age Science History Museum and National Historic Landmark.  Information Age Learning Center (InfoAge) is located at the old Camp Evans base in Wall, New Jersey which is listed on the National Register of Historic Places.

  • InfoAge has an educational mission and its member groups in addition to having unique exhibits are also working to preserve Camp Evans for future generations.

    The location is being developed as a Science Museum and repairs to its buildings are in progress to allow expansion of the Museum.

    You are invited to join this excellent work to save history, honor the communication pioneers of wireless, WWI, WWII, space exploration and the cold war.

  • InfoAge the Science Museum, is a continuation of Camp Evans being a home to new and different organizations.
  • The Information Age Learning Center (InfoAge)received a General Operating Support grant from the New Jersey Historical Commission, a division of the Department of State.

VCF East 7.0 - Computer Development at UNIVAC and Unisys - Al Rollin and Joe LaViola [Both are/were UNISYS Blue Bell Retirees' Group board members.]

6.5 The Vintage Technology Association

The Vintage Technology Association (VTA) is an electronics research group based in Dayton, Ohio, which specializes in obsolete military and industrial technology.  The VTA maintains a collection of over 10,000 devices, spanning over 100 years of electronics and associated mechanical technologies. Our collection consists of a wide range of computers, calculators, test equipment, components, documentation and other miscellany, including a large number of unique and significant artifacts.  Although we try to include specifications or documentation for an item, the focus of our content is historical context.
Our collection includes a wide range of electronic instruments and components, as well as some associated mechanical systems.  Exhibits are organized by device type, and documentation is provided when available. Mabelitini, Curator (userid Accutron)

6.6 Southwest Museum of Engineering, Communications and Computation (SMECC)

The archivist of is Ed Sharpe. This Glendale AZ facility and organization has an eclectic collection of hardware and documentation history items on 49 linked pages.  Their mission is "Preserving Engineering, Communications and Computation History."  Their page has a techmanual level description of the unit, much more than the Legacy Committee has gathered at either the Charles Babbage Institute or at the Lawshe Memorial Museum.  They do have a 422 unit, we await a better snapshot of it in situ.  

This page makes no mention of the 'military' brother, the CP788 nor the UNIVAC type number 1215, reference our other computer chapter.
