A lot of it is written in C; with some work, it can be modernized and
updated. What could be more retro than building the ability to port
CP/M to anything with a C compiler?
Darn, I had this idea, too. I was going to port it to the Palm Pilot.
I looked at the code, and discovered a few things that the owner of
that page (Tim Olmstead) hadn't found.
I think CP/M-68K was cross-compiled under Alcyon C on a VAX 11/780.
(Alcyon also produced an OS called Regulus that was available
for Smoke Signal Broadcasting's 68000 systems.)
The source contains the name "Tom Saulpaugh", and a web search
turned up a book "The JavaOS? Design and Architecture" he wrote.
He's at Sun as the architect of JavaOS for Network Computers.
Tom Mason also works at Sun, and he worked at DRI on CPM-86,
Concurrent CPM-86, and CP/M-86+.
Novell appears willing to release source, but Tim suspects that
there's no one around willing to discover or document what's
available - if anything. For example, the source to CBASIC
should be around, but they haven't released it.

Wow, I thought I was the only one who had ever heard of Alcyon. FWIW,
they OEM'd their compiler from Greenhills, who are still in business. I
remember cracking passwords on our Regulus box (for some semi-legitimate
reason that escapes me). It's not supposed to be possible to decrypt
standard DES Unix passwords (programs like crack don't decrypt, they just
guess at passwords), but Alcyon apparently had a programmer who thought
that his encryption scheme was just as good as DES (it wasn't).
We put Regulus on a 68K-based luggable in 1985 (perhaps the first portable
Unix workstation?), but the company ran out of cash before production
fully ramped.

But such a blast from the past! I didn't think anybody
remembered those SSB 68000 based systems. I saw the ads years ago,
but I've never actually seen one of those.
