Neil,
The computer was mounted in the lower left side of a metal desk. I would
guess the unit size was perhaps 18"x18"x24deep ( just a guess ).
The magnetic core memory section was in the middle slots with card slots
on both sides. Not sure where the power supply was located or how many
slots were in the unit. The only panel was a small readout located on
the top of the desk. Readout consisted of time and automation functions.
( all numeric read out ) programming was by punch paper tape.

There were two versions. The Nova 3 with a 16 slot mainframe and the
Nova 3 Jr with 3 or 5 slot mainframe.
Of course the cards were about 18"x18". Power supply on the bottom,
CPU card above it a FPU card or memory card (1 or 2 cards) and lastly
a controller card..
Access to the interface was from in line pins connected to a Dasher
terminal on the back plane. Connection to peripherals were through a
100 pin (S100) slot card wire wrapped to the pins on the back of the
mainframe.
The older version the Nova 2 had a blue control panel. The flipper
switches were regular (metal) toggle switches. Of cour

Although 12-bit words was not unique, this could easily have been a DEC
PDP-8. What sort of date was this?
