Needs a clean but I'm told it works. Peering inside, no battery leakage and caps look okay - though there's lots of dust. Slight cracks on front cover but otherwise intact.
Okay, took me a while to realize the issue here as this wouldn't boot up. Turns out the answer is in this shot (can you spot it?)
Hints: it wasn't the jumper settings on the adapter, and the succesful chime means nothing 😉
EDIT: I should have been clearer here, the shot shown is actually after I resolved the issue. Before this, I simply got a chime and... nothing else. No sync, no disk icon, no boot - nothing.
Looks like these two capacitors have probably started leaking, from the color of the crud around them. No real damage yet though, it appears. The other caps look to be currently okay.
I'll replace all of them though, 11 on here apparently. I think I may even have them in stock.
Then I guess I should wash the board in IPA (probably water first) before I play with the machine - which I'm quite interested in doing since it looks to be one of the more powerful 68k machines from what I've read - perhaps quite noticeably more than my IIci..?
Yup those caps were definitely leaking. Also, this marks the first time I've used the Adrian Black "push down and twist" method of cap removal. I've been scared to try that before but wow did it make light work of these. Look Ma no damage! 😁
I do love this completely screwless design! Everything removable without tools.
Only issue with it after this amount of time of course is the possibly brittle plastic. So far I've broken nothing but I expect it's probably just a matter of time...
Caps replaced. Believe it or not this board has been cleaned several times, still looks a bit grubby. (Not used the sonic cleaner though). Also, spot the odd one out - I didn't run out of 47uF Panasonics, honest! 😏
Going to leave it overnight before trying it, as I really want to make sure that CPU socket has dried out completely (IPA soaked to force water out, but still).
Been playing around with the LC for a bit, and it is clearly a lot faster than the IIci (my IIci has a cache card but just the base 030, and 128MB of RAM).
Marathon is totally playable in the UI visible mode, though full screen is a bit jerky. Still, it was unusable on the IIci in any configuration, unless you're fine with postage stamp sized view windows.
I really do need more memory on the LC 475 though, even stuff that runs often needs to close Finder windows to do so. It's a bit tight!
