If I ever managed to find a 3100 from 1989, what'd be the overall likelihood that I could get modern of some kind running on what was at one point the world's fastest MIPS-powered workstation (for all of a few months iirc)? Because I think brute-forcing some sort of installation would go great in place of or alongside it.

I know supports the device, so I imagine Linux support exists for this specific machine too, right?

A photo I found online of a DECstation 3100, complete with keyboard, mouse, and monitor. For a time, this was the world's fastest Unix workstation upon release in 1989, though it was quickly outdone a few months later by the first SPARCstation model from Sun Microsystems if memory serves me correct. This machine ran Ultrix, DEC's own proprietary Unix OS, based on BSD. Though Ultrix is long discontinued, NetBSD continues to support it, and potentially also Linux, that topic being the subject of the post to which this image and alt text are attached.

"What is a delay slot? Well, back in the day it was considered cool to expose your CPU's pipeline to the world. Just kidding, it was just a way to save some more transistors."

"The CPU has a register called, literally RANDOM which is supposed to be constantly incrementing, every cycle."

Effective speed about 1MHz - compiles hello world in 2 mins .

Screenshot of Ultrix desktop showing several applications, one being Paint, and in the Paint window we see a hand-written Hello Ultrix!

Also visible a DECterm showing a directory listing and a DXconsole showing UWS v4.5 and Welcome to micro-MIPS.

That's wonderful! Computing at schools, when done well, can have excellent outcomes.

#decstation with #risc I assume?

The #DECstation is now one step closer to being ONLINE

a CentreCOM™ 210T twisted pair transceiver

I have pulled the lid off the #DECstation and it is glorious!

Oh, and what's that snuggled under the floppy bay and behind the RAM?

Excitement!
