Doing some research/thinking for a little retro project I’m looking at, I remembered the old PERQ workstation - c1980. It’s time-frame fits right in my own era although I think I only ever saw one working at that time.
The Wikipedia entry is informative:
But I was just wondering if anyone saw or used one, or even tinkered with it’s (modifiable) microcode - which did seem to be something that a few people did do back then.
(I’m vaguely toying with the idea of my own microcoded cpu engine thing which is why I’ve looked at this)
