Picking up a mystery Classic II tomorrow.

Considering this just came out of a guys basement after 30 years. Initial look is encouraging. Not battery bombed. Caps leaking (of course) on Power board and logic board (nasty on the power board) . So I'll clean it up and recap everything. ADB keyboard and mouse came too....Also got a Powerbook G4 in great condition!

Green corrosion in the connector. Corrosion possibly got all the way up the orange wire?

Anyone know at a glance if those are 1 or 4mb simms?

Recapped the analog board, cleaned, new gear and recapped the floppy drive and recapped the logic board....

Great CRT
Analog board working well
Floppy drive working well

When I turn it on it boots the system fine but no sound for the most part ..oddly I do get a faint chime about one out of eight times I turn it on.

i'm gonna go over the traces and and the four capacitors in the sound area tomorrow.

If anyone has any knowledge or advice, I'll gladly take it. Thanks.
 
yes I already recapped everything. All 44 capacitors later .. 13 on the logic board, 25 on the analog board and 6 on the floppy drive.

really just asking if the fact that it does a half volume chime once out of about 8 to 10 switch ons might be a clue as to where the problem lies? I would assume the sound circuit on the logic board. C4-C9 area. But maybe my assumption is wrong.

Yes, this area, the sound chip is the one near both switches (DFAC) but have a look on the other side of the board, probably a broken trace there.
