On a surplus junket, today, I ran across a 2
dollar chassis that was
listed as a Masscomp 5400 (54S-01) computer. It looked rather like
a DECish based thing with dual height cards, like some sort of laboratory
digital aquisition machine. On the long-shot that it is some sort of
PDP-11ish thing, anyone have any recollection or pointers to any info
on that kind of a Masscomp machine?
Masscomps were 68k based machines, they had a whole bunch of stuff for
real-time and data-acquistion type stuff. They ran something called
RTU -- real-time Unix -- which was a weirdo sysv / BSD hybrid, not fun
to use. If the 5400 is the machine I remember it's a 68020 machine
but it may have a lot of cards for other stuff in. If it *is* the
machine we had it was deeply unreliable. Masscomp got bought by
someone else later on but I forget who, so they sometimes get badged
as some other make.
I would run away, fast.
On the other hand, IIRC this was the machine which was the basis for
the Egan/Teixeira (sp?) book on writing UNIX drivers. It might be
amusing for that reason alone. If it's functional and you have the
space, you probably won't regret the $2 you spend for it.
