Crickets. :)

I found a schematic of the Tesoro Cibla -Vaquero online. It uses a 28 pin PIC (same PIC as the Golden) and I'm guessing it will give me a few clues.


Well searching around I found a few good photos of the Silver uMax PC board and the Golden uMax board. Anyone else notice how similar these 2 PC boards are? The Silver has a lot of pads locations not filled. These same locations are filled in on the Golden. I'm wondering if I could make a Golden from a Silver? Except I would need Golden version of the PIC.

OK, I now have a uMax Golden.

Any of you try to read the code out of the PIC? I'm thinking if I can get the HEX I could figure out how to make my own tone groups. A little hesitant pulling my new toy apart, but it might have to be done. ;)
