This is a game of backgammon, you versus the computer.

Interestingly, it is written in FORTRAN, and the source for the program
is on this disk (backgammon-sideA.ccvf) and the flip side
(backgammon-sideB.ccvf).

I haven't tried recompiling it to verify that the source matches the
binary, or that the source is even complete.

The program runs with v6.78 ROMs, but the display is slightly corrupted
and works better with v8.79.
