Most were 16K machines, I think.

CM-5 panels are their own things, and can be powered up without any
processors. They have a bunch of preset modes, two of which dance the
LEDs in a psuedorandom way to impress people when the machine is not
doing anything.

It was not even a real machine! Just panels bolted onto unused frames
(no serial numbers), with some power supplies bolted inside. If you
look at the film closely, you will also see that the panels are a bit
"dim". Every other row or so was masked with black gaffers tape.
Apparently there is such a thing as too many blinkenlights.

One of the Jurassic Park CM-5 frames holds Dave Fischer's stuff at It used to be mine, but I had no use for the thing.
