Once you have the data for your new eprom's, you would be better off programming 2716 or larger 5V only eproms with simpler programming algorithms, and making an adapter socket to suit the small number of pinout changes. -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
