Also, Tony, if it hasn't been mentioned: Include a header/cable/whatever for in-circuit programming. It'd be nice to load this device with a hex file at a development machine and walk it over to "production" to program boards. Saves walking a floppy around, loading code to a machine, etc. -Rob -- http://www.piclist.com hint: PICList Posts must start with ONE topic: "[PIC]:" PIC only "[EE]:" engineering "[OT]:" off topic "[AD]:" ad's
