Hallo Will,
Ah, I understand:
The HALT instruction of the real PDP11 only stops the CPU whereas simulator also stops
simulating the devices.
By the way, I modified simh 2.6:
The simulated clock ticks at real 60 Hz.
The simulater waits a little bit in each cycle. This saves the real CPU from overheating
and slows down
the execution to a more realistic level.
I can attach terminals, this gives you a more realistc multi user experience.
Greetings,
Wolfgang
