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

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.
