For the UNIX/68k box possibly labelled Unisys, and in the absence, so far, of 
anything more definitive:

Have a look at Convergent Technologies Miniframe. A reasonable amount of info 
around. The pictures at 
http://niki.hammler.net/wiki/Convergent_Systems_MiniFrame
may be helpful - one is of a back panel with multiple serial ports and a couple 
of others. That website is in German but others are available in other 
languages, and anyway a picture speaks approximately 1K words.

No guarantees, but worth a look by the sound of it.

I had the mixed fortune to use one of these briefly in the mid 1980s, primarily 
to use troff/nroff etc for documentation generation and software testing. Real 
development work was done in a platform-independent manner on a VMS box before 
being tested on the UNIX box. The System-V-based (?) Minframe software at the 
time was so unproductive that most of the document production was also done on 
the VMS box (a VAX11/725, for goodness sake, more productive than a hip/trendy 
UNIX box). Write in troff/nroff using EDT on VMS, put through a simplistic 
translation from troff/nroff to RUNOFF, check the output, repeat till it was 
about right, with only the final version being generated from troff/nroff on 
the CT box.

My recollection is that the 68K OS we had didn't do demand paging, just 
swapping, even though if it really did have a 68010, demand paging would have 
been possible (and preferable). 

I believe these boxes were rebadged by various other vendors; the one I had was 
reportedly a prototype prior to being rebadged by Gould. Maybe Unisys were 
doing the same. It may have been Gould's (not CT's) software.

Have a lot of fun

In the late 80’s, I bought from a surplus/junk shop a (by then somewhat 
obsolete) Unix computer, branded UniSys, I think.  It had 10 serial ports; one 
was the primary console, one was intended for a printer, and the other 8 were 
regular user TTYs.  The processor was a 68000 (not 010, 020, or anything else), 
I don’t remember how much memory, and it had an integral full-height hard drive 
as well (60 mB, maybe?).

When I say Unix, I mean real System-7 Unix – not Linux or any other *nix.  I 
thought it was really a pretty neat system – 8 (or 9) users and a printer, just 
perfect for a small office – or my apartment at the time, which had a terminal 
or two in every room.  I learned how to program in Unix on that machine, since 
it matched exactly the System 7 manuals I had. Sadly, time moved on, I got 
married, and got rid of a bunch of “useless junk”, like that computer.

Recently, I’ve been reminiscing and poking around some on the Web to try to 
find information about it, but it seems to have vanished completely with nary a 
ripple.  Has anyone else stumbled across this unit, or at least have any 
knowledge of it?  It was a black case, about the size of a standard IBM-PC, 
with ten serial ports on the back and not much else.  I’d sure be interested to 
know where I might locate data about that unit, or (gasp!) possibly even an 
existing one...
