Hello everyone,
I was lucky to get another non working SE/30 with pattern screen and ethernet card in it. The seller allowed me to open the case to inspect the LB before purchase. Battery has not leaked, the LB was very dirty (first two pics) with some green stuff on one of the sound chip (3430045B) so I brought this one home, gave it a good cleaning with IPA and recapped the LB.
First turn on I got a screen with mouse pointer, but that's it. No chime (headphone jack), no blinking question mark.
I noticed that UE6, UG6, UI6, UE7, UG7, UH7 and Zilog warms up very quickly - floppy port tells me there is +5.1V and +12.7V, but I'm missing the -12V output.
Can someone point me in the right direction? Where should I lock first? (don't have an oscilloscope...)
Thank you
