Also pertinent: Peter Jennings' Microchess for the 1K Kim-1. His page says it "was the first game program sold for home computers", shipped in 1976. http://www

  Was going to bring this up. My father keyed that into his Kim-1 by hand and played it. Definitely predates the one here by several years and also fit into 1K. On a side note, I wrote one that ran on a PIC16 and fit into 4K of flash, while the part had only 176 bytes of RAM. It played over the serial port in a terminal. The 4K is not impressive, but I wrote it in C with a compiler that didn't support recursion because the stack is for return addresses only and is only 8 levels deep. IIRC I could do a 5 level minimax search on it.

  I put a bit of effort into that, basically making C macros to emulate 6502 assembly and getting the program to run on modern machines that way. Peter gives me credit on his site. I often think it would be a good idea to load up his machine code on a 6502 emulator and try to round trip confirm the accuracy of my translation, but time, as always is the enemy.
