Military ? Must have been from the Sperry Univac customer base. Burroughs was mainly banking.
I’m sorry, that is classified. :^)
Unisys still has engineering offices in Malvern Pennsylvania, Eagan Minnesota, Irvine California, Australia, India, and China, with HQ in Blue Bell Pennsylvania. Both the old Sperry and Burroughs lines live on as ClearPath systems, but now execute on Intel processors instead of proprietary processors.
