[volt-nuts] Fwd: Solartron 7150plus - Chasing AC gremlins

[Wim de Jong]

Dave,

Thats the question. It depends on the quality of the cells where the AC 
calibration info is stored.
I'm not aware of a checksum function on these EAROM's.

If it is the AC part, I've some spare parts if necessary... Just let me 
know.

Kind regards, Wim.
