2013 IT Legacy Logo 1. Welcome to our Site:

The VIP CLUB was created in 1980 as the Sperry Retirees Club, a non-profit, social and service organization. From 70 initial members, we've grown to over 1,000 retirees, former employees, and retirement eligible employees of Unisys, Lockheed Martin (LMCO), and their Twin Cities 'heritage’ companies illustrated in the icon at the left. For a printable VIP Club summary flyer and membership form, click here.

     Unisys currently has facilities in Roseville and Eagan while LMCO has an Air Traffic Management engineering facility on Trapp Road in Eagan.

     This web site is a living document of our continuing IT Legacy. With two levels of web page select tabs, we provide Club information as sub-tabs under this Home page and the Contact Us tab. The other page select tabs are an anthology of our Information Technology (IT) Pioneering.  This IT Legacy consists of People who Engineered Computers and Systems at Locations in the St. Paul Minnesota environs and throughout the world.  
    Our volunteers are preserving documents of this IT Legacy at the University of Minnesota's Charles Babbage Institute in Minneapolis, MN and with an exhibit of artifacts, hardware, and posters at the Dakota County Historical Society's Lawshe Museum located in South St. Paul, MN.  Many aspects of our IT Legacy were coupled with corporate sister divisions, i.e. the Unisys Blue Bell Retirees' Club site is at  http://www.

We’ve planned a 1:00 PM visit to the Charles Babbage Institute (CBI) on the University of Minnesota west bank. CBI is the repository of over 1000 documents collected by the Legacy Committee; most now archived in the limestone caves beneath the Anderson Library building. Erwin Tomash, a former ERA employee, is credited with being the CBI founder. Our hosts will be Dr. Tom Misa, CBI Director and Arvid Nelson, CBI Archivist. Send Bob Pagac a note by August 7th if you plan to attend, we'd like a 'head count' estimate for refreshment planning.

For parking, the closest is lot C86/the Law School lot that has shared contract and visitor parking. There should be sufficient space in August before classes. A backup is the city parking next to the Marriott Courtyard hotel, formerly Holiday Inn at seven corners. We’ll have cookies and refreshments available. Hope to see many of you there.

Please note that we changed the start time to 1 PM so that departing drivers can avoid the Minneapolis rush hour traffic.

4. Article for the Month:

August -

July - We add another commercial computer history document with an ERA/UNIVAC/Sperry/UNISYS 1100-2200 hardware design paper from Richard 'Dick' Petschauer. The paper “History and Evolution of 1100/2200 Mainframe Technology” is now available on the Internet. It covers the changing technologies for the logic, memory, and interconnects used in a number Univac commercial computer systems from the 1950s to 1990. It was written by Dick Petschauer in 1990 for the 35th anniversary of “USE”, the Univac user’s group related to the 1100/2200 systems. The 42 pages provide pictures, diagrams, and details of the technologies and their evolution plus insights into some of the challenges in selecting the technology for the next computer system.

June - The  UNISYS, Roseville facility has a history wall. One set of shadowboxes thereon shows the computer systems technology of the '80s. Mike Svendsen and Lowell Benson created this booklet.

May - The  UNISYS, Roseville facility has a history wall. One set of shadowboxes thereon shows the ERA to UNISYS computer systems technology evolution. Mike Svendsen and Lowell Benson created this document.

April - The evolution of UNISYS and their primary computer line is sequenced in this slide set from Ron Q. Smith
