Gotcha, totally makes sense. You're right about the battery holder - one of the posts is completely rotted away, while the other is barely holding on and not long for the world. Here's a pic which will haunt my nightmares for a while:
In any case, I have another IIci I rescued from an e-waste place last year - that one is in much worse cosmetic condition, but didn't seem to have nearly as much damage to the motherboard. If nothing else, I should be able to combine the case of this newer one with the mobo of the older one and end up with something workable...
I've seen much worse (including my very own Classic II which had a Maxell battery that took out the RTC, about 10 traces, and a few other things in its path and also destroyed the chassis in the process)...
There won't be much, if anything, keeping the battery holder attached anymore - with a bit of a nudge it might just come off on its own (mine did).
I honestly think that could probably be saved, but it would take significant time to repair the trace/component level damage... In either case, definitely keep the IIci board as a spares board or pass along to someone who may be
Sighhhh... the battery did indeed puke its guts onto the logic board
Here are some updated pics showing what looks to be fairly severe corrosion / battery-juice damage: https://imgur.com/a/FloNF6d
The corrosion on the RAM looks pretty bad, and the battery holder itself (not just the pop-off cover, but the whole battery chassis) is hanging on by a thread. I have only the most rudimentary soldering skills and haven't restored anything nearly this bad before, so feedback is very welcome. Does this look fatal, or could it be repaired?
Thanks for any insights,
Picture might not be that good, but basically:
* all SMD parts are resoldered, except for the F573 for which I haven't received the replacement part yet
* all damaged traces should be fixed, everything had its connections checked thoroughly before being soldered back
* a few vias were bad so I had to get creative with my bodging... dealing with 0.2mm wires is a lot of fun
* my neck is screaming at me
I will do the through-hole parts tomorrow
Once I receive the F573, I'll be able to give this a test run. I
