    SE/30 stuck at boot with raster but no cursor

    I thought I'd provide an update...with a good outcome. I decided to follow the advice provided by @mrkirkby and double-check the ADB chip. I had one or two connections that were suspicious enough that I decided to remove the ADB chip, clean it and the pads, and reinstall. Sure enough, that...

    SE/30 stuck at boot with raster but no cursor

    It's not a power supply problem. I used my SE board in my SE/30 and it booted just fine. I believe I narrowed the culprit to a faulty filter, 155-0007-E located at L13 on the SE/30 board, and marked as L1 LNET on the schematics. I think the pin numbering is incorrect on both the Apple SE/30...

    SE/30 stuck at boot with raster but no cursor

    I checked my ADB chip again from a continuity standpoint - checking both the solder joints at the pads for continuity as well as via the schematic to neighboring locations - and continuity checked out fine. I also checked all three of my resistor packs as a control case for RP10, measuring...

    SE/30 stuck at boot with raster but no cursor

    Awesome, thanks for the info. One more data point to add. I had a "doh" moment and decided to test my SE/30 board in a working SE machine. Ended up with the same result - chime, gray raster screen and no progress to mouse pointer. Voltages measured similarly on the SE/30 board: +12V rail...

    SE/30 stuck at boot with raster but no cursor

    I'm following this thread because my SE/30 just started showing the same symptoms - boot chime followed by the gray raster screen and no mouse pointer. It worked fine after a logic board recap and only just started showing this problem. Another possibly related problem is in recent weeks when...
