README.MIT
readme from MIT
contains history, and instructions
spacewar.mac
spacewar 3.1 (24 sep 62) retyped at MIT from a listing,
originally assembled using a Perl macro-expander and assembler,
and run under a Java PDP-1 emulator.
This version modified by Phil Budne to assemble under his
version of "macro1" (see below)
Note that low memory (locations 6 thru 31) contains various
manifest constants which can be tweaked to alter the game's
behavior!
spacewar.rim
above assembled by Phil Budne's macro1
PDP-1 RIM of "loader" followed by loader blocks:
PDP-1 simulator V4.0
sim> set dpy enable
sim> attach ptr spacewar.rim
sim> boot ptr
controls compatible with MIT Java simulation, see README.LCS
or display/README from your SIMH distribution
munch.mac
"munching squares" display hack, reconstructed
from world.std.com/~dpbsmith/munch.html
munch.rim
binary of munching squares.
reads console switches:
Upto 18 simulated console switches, toggled by hitting keys:
123 456 789 qwe rty uio
space bar clears all switches.
assembled with '-r' option, so it can be "loaded" directly:
PDP-1 simulator V4.0
sim> set dpy enable
sim> load munch.rim
sim> run
macro1.c
Phil Budne's version of the MACRO cross-assembler
