. 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.
