Have you (or someone else) got OS media, just in case we need copies for
ours?
Shame, that. Ours has graphical capability; four BNC sockets on the back
and a big CAD monitor with it (which is what drew me to the system - one
of my big interests is in graphics workstations)
Masscomp did
indeed make multi-cpu machines,
Yeap, each chassis can have up to four CPU cards. I think the dual
chasssis machines could have up to eight but I'd have to check on that. and also had an
os called RTU (Real Time Unix).
Yeap, I just sent that manual to Al K. I have at least three other
manuals here. The CPU in mine is 68020. It's card looks
similar to Multibus but is
longer and has different connector. (I'll post pictures later.) It plugs
into the SMI bus. There's also a Multibus chassis in them for the IO cards
AND there's also STD+ card sockets in them for data acquisition cards. STD+
is an enhancment of the regular STD bus. Some of them also had VME sockets!
The use of four different busses really surprised me.
Heh, that does seem to be slight overkill.
They had early
successes as graphics/cad workstations,
so yes they had mice.
Some did, some didn't. Some only used termials but others had graphics
capabilities. I think mine all just used terminals. Masscomp was bought by Concurrent,
yay! :-)
so there used to be some info on the concurrent
users
group web pages at www.ccuruser.org. That seems gone now,
but archive.org might help you dig up some old stuff there.
There'll be lots more there soon! It uses an Excelan EXOS 201 Intelligent Multibus
Ethernet Controller. I
have manuals for it. One of them has already gone to Al.
I wonder if that's the same one as in my NCR Tower (which is also
multibus for the IO boards). EXOS rings a bell.
