Well Parallax programmer required :( well as far as it goes for Stamp I, AT90S1200 will alwasy fit Stamp I programs. Also Mel Basic Compiler could be used for PIC16C84 to be programmed with Basic Stamp compiled code. well thats not free. there are some more free solutions, but currently no one of them are truly Stamp I compatible or very useable. antti AVR Basic Light NOW Available - Look for September Specials http://avrbasic.com Free AVR Basic Compiler Demo Edition
