UTS (Mainframe UNIX)
Encyclopedia
UTS is an implementation of the UNIX
operating system
for IBM mainframe
(and compatible) computers. Amdahl
created the first versions of UTS, and released it in May 1981, with UTS Global later acquiring rights to the product.
s and their successors:
in 1975 to port UNIX to the IBM VM/370 system. Team members there were Tom Lyon, Joseph Skudlarek, Peter Eichenberger, and Eric E. Schmidt
. Tom Lyon joined Amdahl in 1978, and by 1979 there was a full UNIX version 6 system on the Amdahl 470 being used internally for design automation engineering. In late 1979 this was updated to the more commonly ported UNIX version 7. The commercial versions of UTS were based on UNIX System III and UNIX System V.
