Well he doesnt believe me that the A3000T SCSI NVRam settings are stored on the batt. He doesnt have one installed. This could be a solution.
Well, I don't believe you either. C'mon, stored on the batt? That Amiga 3000T used a standard -for the time- rechargeable "barrel" battery. It has no circuitry for anything like NVRam.
Now, if you mean powers the NVRam, sure, but that is entirely different.
