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
in order for "set dpy enable" to be successful, you must have
compiled the pdp1 binary with libSDL or libSDL2 installed
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
in order for "set dpy enable" to be successful, you must have
compiled the pdp1 binary with libSDL or libSDL2 installed
macro1.c
Phil Budne's version of the MACRO cross-assembler
