Howdy folks. I got my FV-1 pedal put together (well, will as soon as my pots arrive...) and in the mean time I've been playing with writing my own patches. I got a batch done and converted to Hex, but for some reason I cannot get my PICkit2 to spit them onto my chips.
Hardware: PICkit2 and ZIF socket board, 24LC32A EEPROM chips
Software: PICkit2 v2.61
I have the chip loaded into the proper lane in the ZIF, the jumpers are properly placed, it can read the EEPROM fine.... but it fails at address 0x000000 every time I try to write to the chip. I've tried all 8 combinations of the Ax check boxes to no avail. I've tried both 5v and 3.3v
Any ideas?

I figured it out! Turns out the ZIF board I got is meant for microcontrollers, not EEPROMs. Had to breadboard up a little thing to get the pins going in the right order.
Found the schematic on DIYSB and it fired right up. Woo. (though I have the pins on the pickit2 numbered backwards from that, same diff)
