Is this Bernhardt Baehr's excellent emulator?

Can't help atm as my mac with the emulator on is hors de combat with a
failed monitor - need a vga adaptor...

Ah...must be Mr Baehr's emulator :-)

Halt the PDP-8
Set memory size to 32K or more
Go to the RK8-E window and mount the DECpak "Pascal-S disk" in drive 1
Restart the PDP8
Assign a logical name to drive 1 (not really necessary, but it saves
typing later). ie "ASSIGN RKA1: B:"
Type "RUN B:PASCAL" (seems like you've got this far already.)
When the command prompt appears (an asterisk) type the name of a
Pascal source file to run, such as "B:BENCH.PS" - this file is
usually included with the emulator.
The file will be compiled and run.
A really great emulator, but I've not worked out how to load TSS-8
on it yet! It's worth getting an old Mac just to run it :-)
