I know it's a long shot, but what the heck.

Was there ever any work on putting CP/M68K on a Sun3?

I am looking at all the M68K systems I have and looking to see if
there is any chance of getting CP/M68K running on them.
I currently have:
Tandy Model16 (runs P&T CP/M68K)
a Sun3
a bunch of 68K Macs
a couple of oddball QBUS M68K boards

Would be fun to have CP/M68K running on more than just the Tandy.

Is there any kind of a porting kit?

CP/M-68K does not (AFAIK) have any support for virtual memory. I guess
it would run on a 68010 or 680[23]0, but this might be a bit
pointless...

OS9-68K might be a better choice for the Sun3.

The original distribution included everything you needed which is how I
started. From reading the S1S9 record format, hand patching the hooks to
my dirt simple BIOS, to using the CP/M-68K tools to assemble the next
BIOS, etc. The distribution disks and manuals can now be had for free.

Since you already have a working CP/M-68K system you get to bypass all
of those fun first steps. If you have good documentation for the target
hardware it shouldn't be very hard.

Why? Or do you jkust mean it wouldn't make use of the full potential
of the hardware. Well, if the desire is to run CP/M68K it would be
doing exactly what was wanted without VM. :-)

Not free. Not available in Source. And if MicroWare ever did a port
it is probably not avialable anyway.

For free? really? The manuals too?
If so - where?

Caldera released them under a "free for non-commercial use" license
years ago.

Ah, I see. Thanks!

There are postscript files of the CP/M-68K manuals over there, tucked
away in some .ZIP files.

The CPM68K "System Guide" has porting instructions in it. It is pretty
good, as I remember. The System Guide was distributed with the other
manuals.

I spoke to a guy at Compupro many years ago (obviously), who had a 68020
IEEE-696 board running CPM68K. He said it required very little work,
just getting the extra stack pointers initialized. They already had a
BIOS for all of their disk and IO boards for the 68000 boards.

If you can get adequate documentation on the Sun 3's it should be
possible to port. Any memory manager hardware should be possible to
disable, systems boot in physical memory mode. The video system might be
painful, but early phase development could use the serial port for the
console.

CPM68K was originally developed on the Exormacs systems.

Good Luck,
BobH
