Apollo DSP90-3M

As I remember the DSP-90 was a rockin' machine for its time...the
'king of servers' machine. Mentor Graphics had a bunch of these sitting
in a room with LOTS of Air Conditioning in it...to act as a simulation
farm for their logic simulation software. As I remember...I think that
the machine used all ECL logic for the CPU. It sucked up a lot of juice,
and made a lot of heat.

I seem to remember, but not completely sure, that the CPU was essentially
an ECL implementation of a 68000...a comparatively very fast 68000.

It should be preserved if possible...Apollos in general *could* have been
the engineering workstation of choice had Apollo not made some silly
'closed architecture' blunders. Their OS and Network environment has
solid features that today are still not real solid in the Unix/NT worlds.
