Yes. Running under OSX.
I am running OS8 on a pdp8 simulator in my iBook.
Is this Bernhardt Baehr's excellent emulator? I get the . prompt,
I run BASIC, type in the single line
10 PRINT "HELLO WORLD"
RUN
it prints out the header, then prints
ME 10
Well, it's a very simple BASIC statement, did I get
it wrong? (or is the simulate broken?)
Can't help atm as my mac with the emulator on is hors de combat with a
failed monitor - need a vga adaptor...
It's a nice simulator with a front
panel-blinkenlights
Ah...must be Mr Baehr's emulator :-)
Anyone know how to boot the PASCAL-S Disk? The
simulator has a menu
selection that
fat fingers in the RK8-E boot loader (strictly cheating I know.) but
once that is set
in motion nothing seems to happen.
From the docs:
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 :-)
