I was unfamiliar with that model. UNIX machine. Here is more info:

Funny enough, a few years later Commodore offered a port of Unix System V that ran on the Amiga 3000, I actually played with it in my University.

They had an interesting hack to connect to a high-res monitor. Timing wise they had to stick to the standard TV timing otherwise regular Amiga software would not work. So they created a hack where the Amiga would send 4 screens of pixels that would then assembled and sent to a high-res monitor. Screen refresh rate was very slow though.

Oh wow, it ran MWC Coherent!

I still have a (printed on dead trees!) manual for Coherent 3.2 (286 version, circa 1990-91) kicking around. Ran multiuser (login via tty or virtual terminals on the console) in 640Mb of RAM, off a 10Mb fully installed setup. If I remember correctly you were limited to 64Kb code & 64Kb data per process, though ... (Coherent 4.0 removed the addressing limit).

Wow. That could have been something! Might have been a commercial flop, but it would have exposed a lot of young folks to some useful ideas a decade or two before they otherwise would have been exposed.
