Backport Imlac games to PDS-1 #1876

Open larsbrinkhoff opened 4 years ago

larsbrinkhoff commented 4 years ago

The games CRASH, PONG, and SWAR have been modified to run on the PDS-4.

If possible, use @tuban's files as a guide to update source code to run on PDS-1 again.

CRASH shows promise with these simple changes:

The other two doesn't do as well.

By the way, how to load a program on top of SSV:

  1. Have it begin at 10000
  2. Type :IMLOAD PROGRAM
  3. Type Control-Shift-TAB to start bootstrap loader
  4. Program loads
  5. If start address is 101 it comes back to SSV; type Control-Shift-ESC

I heard @dlebling618 ported Spacewar to the Imlac as an exercise to get to know the machine. I wonder if the source code here is an ancestor of that version?

The title "CHAR SET 2" is a bit strange.
