Jumper setting
--------------
J2 SCSI Connector Pin...
I have a classic with even more damage from the leaking battery. Removed RTC and sound chip, D1, D2, Y1, C1, C2 to clean beneath and repair a lot of tracks. Tested the board before replacing these components.
probably combination
analog board I still see capacitor fluid residu from the old capacitors, please clean that
you can use pp1 to adjust the 5v/12v voltage , take care, high voltages around!!!
adjust the 5V a bit higher, but also measure 12V so that it is not too high
logic board probably...
did you try resetting the PRAM?
Reset PRAM (hold down command-option-P-R while pressing the power button, continue holding these keys down until the computer chimes at least 3 times, then release).
could you try booting without the battery present
Can someone confirm the bomarc schematic for the classic II is wrong regarding pin 1 and 2 of the DFAC?
wrong version (pin 1 connected to pin 2 and swapped)
corrected version
Second question
where does the via next to C11 go
Could you show the ram configuration you used for testing?
I am also from the Netherlands, maybe I can help if you don't succeed.
