### TVWAR 20

From the previous archive file.  Runs on ITS and draws on a Knight TV
raster display.  The file containing bitmap graphics for the ships is
missing.

### SW.MAC

Stanford AI Lab, 1972 and 1978 versions.  For the WAITS operating
system; uses both PDP-6 and KA10 processors in parallel.  Draws on a
III vector display.

### Information the LDS-1 version

> LDS-1 Spacewar was amazing to watch, though it looked like it took quite a lot of practice to play.  There was a box with a row of toggle switches (maybe 16 or 18 of them?) and you used them to control the ships.  The ships could move around freely on the screen, iirc there was a star (sun) in the middle of the screen whose gravitational force was a game parameter, and other cool things like that.  I don't know of any modern video game anything like it.
