I'm pulling the plug on the project. However, I really do not need to get around it, since just running the EasyProg to a breadboarded socket works fine. For that matter, you might consider adding an "accessory board" to your product line, for people who want to use the EasyProg with a dsPIC (and presumably also for the 24F line), since I don't know of another competitive board right now given that the 28-pin dsPICDEMO board won't work. It wouldn't take much -- just a circuit board, a 28-pin ZIF socket, an RJ12 socket, a diode, couple of capacitors and perhaps a couple of bells and whistles (some option jumpers and a couple of LED's). You could probably sell it for $9.95 and still make a good profit. :-) The dsPICDEMO board is $79. Thanks for your help and suggestions, as always.
