IIsi has broken power supply, IIfx has corrupt motherboard.
Lots and lots and LOTS of parts...
IIfx RARE RAM!!!
I am making a bid for some keyboards/peripherals, but the Macs themselves and all internal hardware is up for grabs.
He is prepared to ship, so act fast!!!
I'll bet that IIsi just needs a PSU / Logicboard recap and it'll be up and running
I'd be interested to see the extent of the battery damage to the IIfx's logicboard, depending on it's severity it may be repairable (One of my IIx's had a battery leak, had to lift a couple of ic's, clean their pads and resolder them and repair a couple of traces then it was back up and running)
Sadly, this is well beyond my technical expertise...
