Trying to confirm the operation of my EEPROMs (module identification), not much luck yet.

Soldered a jumper on one board to enable writing, and it seemingly accepts write commands but refuses to reply to a read request. Except it worked once. No idea why.

On the positive side, the I/O expanders work OK, I've wired a couple of pins together to confirm that (these are part of the same chip as the EEPROM, PCA9500)
