I am curious about what is in the HSC70 but the the
door is locked and
the key is lost. There should be a PDP11 and several HD's inside, at
far as I know.
There's not a PDP-11 per se. There is a J11 processor, on a special
bus that is not mechanically compatible with anything else, and
electrically somewhat similar to a Qbus but not interchangeable, along
with an additional channel bus.
No HDs inside, just an RX50 floppy drive.
