Hello Tom, Exactly, this was the idea. Footprints J9 and RA3 in the EVM unit I have are not populated, so leads A0, A1 and A2 are floating. I assumed keeping the "good address" would be as easy as not connecting the A0, A1 and A2 pins. The drawback of this plan is that I may break something with the soldering/desoldering. It's "one shot". The cabling and routing is also more fragile, tickier and arguably uglier than placing a blank EEPROM on a propper footprint on my custom board. Martí
