Does anyone know if there's a single person chess game for the TI 83? I know there's a 2 person game for the 82 (it doesn't seem to work to well when converter to the 83) Back in the early 80's when computers weren't too sophisticated - I can remember playing a chess game against a computer that only had 16k of ram - so I know it can be done for the 83. Come on - Somebody out there must have tried this?
