It was my understanding that the 16C parts are one-time programmable, so if the chip is scrambled, it might stay scrambled. That said, you could probably replace it with a 16F part. On the page on Microchip's website, they suggest the PIC16F723A, but I haven't checked whether it'd be pin-for-pin compatible or if it just has the same features.

(It's a MIDI widget that basically adds chord memory function to any MIDI keyboard see here: http://matrixsynth.blogspot.com/2008/01/waldorf-gekko-midi-chord-memorizer.html ) I think that the PIC in it got screwed up somehow. It's a 16LC63A. I don't suppose anybody on the list can point me to someplace that might have code for this bugger?
