I've got a half dozen different source trees for mc680x0 Unixen, but
nothing for an mc68010 CPU + mc68451 MMU. I know Unisoft did some. I
don't know if the Motorola ports (like for the VME/10) were Unisoft or
done internally.
Did any '010+'451 source trees survive to escape into the wild?

the will probably be 68000
unisoft kernels i've used weren't 010 with the 451
i'll have to dig around for what bits of the 451 kernel i still
have around. unisoft kept the mmu parts pretty well isolated since
the did so many hw ports

Did Unisoft distribution tapes normally include sources?

A quick google search found:

I have an ancient Unix system made by ProComp in Switzerland that has a

as some System III variant. Would surely be nice to see Linux running on
that machine ;) but I should better go and work on the MVME147 port ...

Motorola System V/68 Release 2 versions have been distributed as obj and
source. They will run on MVME115 and MVME121. Both are using 68010 and
68451 MMU

I'd be interested in looking over something along these lines. I have
some 80s hardware that we put a 68000 + 68451 on, but it would easily
take a 68010. It was going to be a massive wad of async ports and
some sort of WAN port (X.25 was one technique). It never made it out
the door as a product, but I have the prototypes in the attic. Dual
Z8530 serial cards (4 ports) with a Motorola DMA engine or 8-port PIO
serial cards on top of a pedestrian 68000+68451 design w/2MB of 41256
DRAM and an early Sony 3.5" floppy drive - designed 1983 to 1984 ISTR.
We used a Perkin-Elmer 7300 Uniplus box w/System III as our software
design workstation because it was an inexpensive way to get 4
developers cranking out C code to 68000 object code to link into our
own format for the hardware target. I still have the P-E 7300...
tried to sell it at Hamfests 20 years ago and nobody was remotely
interested.
We never finished the app for this thing, but I always wanted to see
about tossing UNIX on it - plenty of serial ports, and at least a few
hundred KB of removable storage... just have to figure out what to put
on it in the way of a mass storage device - perhaps hacking one of the
DMA serial cards to add a 5380 SCSI chip in place of a serial chip.
So... short form - I'd love to read over some 68K UNIX code to see
what it would take to make it run on orphan hardware from 30 years
ago.

If that?s your goal, I think NetBSD will run on 68000 & 68010 hardware with an MMU
(Sun or 68451).
