I bought a fixer upper Model 102 not too long ago. What I discovered on that was that not only was the Nicad battery dead (not unsurprising), it would not power the RAM while turned off because battery acid from the old battery had leaked down the side of the board and etched a hole through the trace that would allow it to do so. The RAM would power on while the power switch was on, but with the memory back up switch in the on/off position it made no difference. I would suggest checking for this... check to see if you have power to the RAM while the power switch is down. There is a long trace on the edge of the circuit board that supplies this backup power and in my case I had to wire a short jumper to bridge the etched out section. All is well now.
