Thanks, I'll look into it. A nuisance with ICSP can be isolating the PIC from other circuitry. I'd normally use a 4x2 header and 4 jumpers but that seems a waste for infrequent changes. 4 solder blobs are almost costless > Olin's programmer (the professional one, not so sure about the > EasyProg) is capable of dealing with some not very nice ICSP > conditions.
