I could not yet afford a Solaris workstation back in the days, so I ran out and bought Coherent.

The Mark Williams Company was roughly five miles away from my home.

Thanks for the memories!

In reply to Allen Garvin. You'll need a drive, naturally. In this article, it mentions the FC5025, a USB controller for the 5 1/4" disk drive. And of course there is the KyroFlux if you need/or want to take far more detailed disk images.

I’ve got a set of 5.25″ floppies of Coherent III. I haven’t installed Coherent in over 25 years. Actually, I preferred Minix at the time anyway.

What’s the preferred way to pull data from 5.25? Searching, I can’t find any USB drives…

Did anyone actually get this (coherent) up and running?

In reply to mrRadio.

check all the RCS files, you should be able to pull out older versions.

there is tonnes of userland stuff, it’s scattered all over the place, pick a command and dig around.

From what I see what is missing is almost everything pre version 2. There is only mentions of the PDP-11, 68000 and Z8001 in libc and a few other places.

In reply to neozeed. I mean source archive contain Coherent 4.2.12 kernel source and some libraries but does not contain userland src. It would be great to build 4.2.12 or 4.2.10 from sources (4.2.14 very unstable kernel). Coherent 3.2 in mwc\gtz\relic\d\ too old :).

In reply to neozeed. pcem wasn't much better, it just has a CPU fault and dies (I tried some 486 boards)
