Hi shred,
out of interest, were you involved in selling Australian Mac 128K machines? It just seems unusual that they were 110V when the "european" 128K models were all 240V - many later Macs sold in Australia shared Apple European part numbers.
Very interesting - makes me wonder where my two 240V 128K Macs originated from
Mine are both bone stock, and appear to not be upgraded (eg. with a later analogue board, 512K board). Apart from repairing the RAM in one, both have been rock solid I have to say - unlike many Pluses from a couple of years later which I've found have several analogue board faults. I appreciate there are probably one hundred fold more Pluses out there in the wild, however
