You can see the source code here or download the disk image.
To start the game BRUN LISP and at the ":" prompt type (LOAD MASTERMIND) to load the Lisp workspace
with the game. Finally, type (MASTERMIND) to start the program. Don't forget to make your guesses a
list! Ie, if you want to enter 2 5 4 3 9 you type (2 5 4 3 9).
The source code is in the file MASTERMIND.LSP. To edit it use the included LED
editor, which is what I used to write it, or use a real editor. Sadly, Lisp itself will not run under ProDOS so we
are stuck with DOS 3.3. BTW, my attempts at particle swarm optimization in Lisp are also on the disk image, if
you are curious.
The game is simple, just follow the directions. It was fun to write, enjoy!
