The oldest/weakest I've personally run UNIX on
was an 11/24 w/dual
RL02 (10MB each) and 2MB of RAM. It's far from a record. If I can
find an affordable EAE for my PDP-11/20 and figure out how to sub the
swap disk with something other than an unobtanium fixed-head disk, I'd
run it there, but that's a long-term project.
I haven't (yet) personally run it, but Accent (the grandfather of Mach)
on the PERQ workstation supported multiple personalities, amongst them
UNIX. Given the speed of Accent on my PERQ I cannot imagine that UNIX
running as a subsystem under it would win any speed contests. (The
PERQ's microcode engine ran at about 5Mhz, and it was designed to
execute bytecode instructions quickly. The bytecode throughput for
Pascal was about 1 million "q-codes" per second, I don't know if the
bytecodes for the UNIX/C side of things on Accent was similarly fast...)
(I also need to give PNX a try one of these days, I have a spare SA-4000
drive that I plan to use for this purpose when I get the nerve to swap
it out...)
There's an interesting writeup on the trials and tribulations of porting
UNIX to the PERQ (and a lot of other interesting PERQ stuff) here, if
anyone's interested:
