Specifically, I think that it is because the demo board requires its own power supply, and of course the EasyProg won't go along with that, although the ICD2 will. OK -- no big problem. I've got a 28-pin ZIF socket around here somewhere, and will make up something on a piece of perf board and just run the RJ12 cable from the EasyProg to that instead of trying to use the demo board (for the purpose of using the EasyProg to program a 3013 chip, I mean). Just running the 5 lines from the RJ12 cable to the appropriate pins on the 3013 would work without anything further needed, wouldn't it? (MCLR, Vdd, Vss, PGC and PGD). Not really ICSP, I suppose, but just more of an auxiliary ZIF socket to the one that comes with the EasyProg. (I'm not ignoring your suggestion of a couple of 47 pf capacitors -- I'll stick those on the perf board). -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
