I have a commercial device with a defective OTP chip that is unavailable=20
for repair. The current scheme is to fabricate a PIC module on a PC=20
Board that plugs into the OTP socket to provide appropriate power and=20
port connections. The osc & pgm connections would be on the new PCB.=20
Software would need to be written from scratch.

This is a hobby/academic subject for me and I have yet to work with any=20
PIC's other than DIP. Until I develop the skills needed for a smaller=20
package, my project is on hold!
