Chip says "Toshiba TC97208AP Japan 4F1518" This is indeed out of a ChryCo vehicle. I've got one modified with a atmel eeprom that will program in circuit, without much more than serial cable and switch to bootstrap the hc11... Managed to get the st flash version working, just this chip eludes erasing and programming. I've seen almost every page on the internets with that part number on it that gargoyle would turn up. Thanks for your help. --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
