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.   Some aspects of our IT Legacy were coupled with corporate sister divisions, i.e. the Unisys Blue Bell Retirees' Club site is at  http://www.

3. Next Event Summary

September 10, 7:00 PM - Please join us as LMCO employee Steve Koltes reviews over 50 years of our company systems developments in the Air Traffic Control environment.

If you have flown commercially any time since the early 60s, you’ve had safe take-offs and landings because of systems developed for the FAA by UNIVAC/Sperry/UNISYS/Lockheed Martin. Steve will present the history of our involvement with the FAA and the functionality of air traffic control systems. Tidbits to hear about are: The 30-bit IOP design was in service for 40 years  and the Naval Tactical Data Systems’ use of UNIVAC TYPE 1218 Computers to process Identification – Friend or Foe (IFF) transponder information became the basis of the FAA system to identify flight numbers and aircraft types in our skyways.

Future VIP Club hosted programs and events are listed on our calendar page. TOP

4. Article for the Month:

September - A 'bottoms up' chronology of semi-conductors used by the defense groups of ERA/UNIVAC/Sperry/UNISYS/LMCO by Larry Bolton.

August - A review of Dr. Thomas Misa's Digital State book by Lowell Benson.

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.
