No problem with that for the S-socket. I do believe that the P-socket chip will have to have a fixed oscillator config.

As I've said all along it's a universal demo board, not a universal programmer. BAJ -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
