Wow! That's very cool. Can we also assume that the
processor(s) in
those boxes use the PDP-10 instruction set or have they ported TOPS-20
to another processor?
The former. TOPS-20 has a number of PDP-10 assumptions built into it, mostly
because it is written in PDP-10 assembler, and would be difficult to port.
