That's what I would have thought, too, but there isn't any battery that
I can see on the PCB (nor does it look like there has ever been one).
Were there other methods for storing settings aside from battery-backed ram?
How about an EAROM? I think that's what the VT100 uses. Is there an
ER1400 chip?
It is, of course, possible that the battery is elsewhere in the machine.
Maybe in the PSU area?
