I remember the Masscomps we had fondly. The ones we had were 68000 based
and they had two of those CPUs running in lock step (or something, Clem
will correct this, he was one of the main devs at Masscomp) because the
68K didn't do VM right. I can't remember the details, it was something
like they didn't handle faults right so they ran two CPUs and when the
fault happened the 2nd CPU somehow got involved.
Clem, what model was that? And can you provide the real version of what
I was trying say?

I remember Masscomp... We used one (I forget model) in the field in the
late 80s in the back of a tractor trailer. We'd capture radar signals with
it because it allowed data acquisition to not be swapped out. It was a very
expensive failure if, just as you started getting the short radar return,
something like system logging swapped you out for a little! I used to regularly compress sources of various
distributions (not UNIX, but
inn, pine, elm, etc) that I compiled, just to save space.
And that was in the early 90's when I could buy a 1GB SCSI drive for $1000.
I can't imagine working off of the early hard drives...
I was sys admin for a Masscomp with a 40MB disk and 20 users. That
was, um, "fun".
