    Missing -12V voltage on SE/30

    you're right, thank you! Then this board is in full working order, I was just surprised and had the -12V from the Classic board in mind...

    Missing -12V voltage on SE/30

    Hello, I recently recapped this SE/30 board and it works - I got the chime, the mouse pointer appears and the blinking question mark too. On J12 pin 7 there is -11,7V, C9 negative side also -11,7V - but not on floppy port pin 5 - here my DMM is jumping around and goes crazy!?! I also have solid...

    Macintosh Classic II recap needed?

    @gagigu Could you please post a picture of that logicboard? I could help to recap that board but want to see a picture first. I'm near Frankfurt, Germany.

    Recapped SE/30 - only the mouse pointer appears

    Thank you for your help @LaPorta and @croissantking I've desoldered and cleaned the SCSI chip, added some PLCC sockets to swap and test with another SCSI chip, but this didn't solve the problem. Next will be the VIAs... Troubleshooting would be much easier with an oscilloscope

    Recapped SE/30 - only the mouse pointer appears

    I removed and cleaned the SWIM and Z8530 with no improvement. Will go next to sound chip. Thank you I am not sure if this points me in the right direction. Maybe I´ll try Applecat later

    Recapped SE/30 - only the mouse pointer appears

    The mouse pointer moves smooth at all on both ports. Yes it was on floppy port... In order to understand the failure, the boot sequence must be known and I don’t. It seems that one of the last step is not completed/missing

    Recapped SE/30 - only the mouse pointer appears

    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...

    Classic II - Logicboard Rev. B troubleshooting

    I'm sorry for late reply. I pulled out this Classic II and changed the ROMs as seen in the picture from @marcelv But that changed nothing, black screen, no chime. I resoldered the caps again - nothing. After that I desoldered the EGRET again and found out that when I touch pin 2 of the EGRET...

    Colour Classic - identifying resistor

    Thank you, what performance should be used, 1W should be enough? Do you have a schematic of the this analog board?

    Colour Classic - identifying resistor

    Hello, I got a Colour Classic with working logic board (no battery damage, I replaced the caps, it chimes when you hit the power button) but the screen won't torn on. I replaced all capacitors on analog board too, and found a toasted resistor "RF19". Bomarc schematic doesn't include schematics...

    Who has a iMac G3 with either a Sonnet Harmoni processor upgrade and or a item that uses the Mezzanine slot?

    Which of these USB/FW cards would work with a Beige G3 running OS9?

    I‘ve a working Sonnet Tempo Trio in my G3 desktop, firewire works with 9.2.1 and it powers my Lacie Ego hardisk. I haven't tried whether you can boot from it.
