Tiny Pascal for TI83p and TI84

Tiny Pascal for TI8x is a full Pascal and Assembly language tool chain for Texas Instrument TI-8x calculators. It allows production of programs and application for TI83+ and TI84 calculators. The benefits are : · All the features of assembly programs and applications are available without the inherent complexity on Z80 assembly programming · Programs will run much faster that TI-Basic equivalent · A standard library is available (gotoxy, ClrHome, flush, crlf, …), and it will be expanded when needed · Built in access method to TI8xPlus system routines from Tiny Pascal programs · TI-8x menus support To show what you can do with this tool chain, we have coded an Othello/Reversi like game.
