an 8080
Development system/simulator to test flying code on line for a mere
$25.00/hr
I know that as they also had the same for 8008 and I'd used that.

Interesting comment. I wonder if that's how Gates/Allen would have done it.

So here's the punch line. Does anyone know if
someone ever recreated an 8080
emulator to run on the PDP-10 (under SIMH, since I don't have a PDP-10)?
Good

can't remember the details. Rich Alderson would be a good person
around here to talk to about it.
