thanks so much for your help. I guess the next step would be to put the scope on various parts of the card but I'm just lost as far as what to look for.
I did order another video card. Just couldn't help myself 50 bucks on eBay so that will definitely narrow things down. hopefully that card...
this card is the "BCGM0322 high resolution display video card". Everything I've read indicates it is compatible with the Apple M1212 monitor. I know that the monitor is functioning correctly because the guy I bought it from demonstrated it for me a few days ago and it was fine.
again, the boot...
tried a boot floppy and it definitely stays in the drive and makes all the correct sounds like it's loading the operating system. However, still white screen on the monitor.
I have not tried to boot floppy but I will tomorrow. I'm so used to working on SE's and SE/30's that it didn't occur to me that these might behave differently without a startup disk. if that's not it, I will definitely look into the 74 series logic chips.
OK also I'm gonna check the Nuchip and nubus slots with the scope. Any idea which pins I would need to check specifically? If not I can go through the schematic.
good point. Will do this week but I need to order more caps unfortunately. Any chance these will at least run without caps like an SE 30? doesn't even have the axials.
Recapped Power Supply is putting out 5.1 v and 11.94 v.
floppy drive is also working flawlessly with cleaning and new eject gear. Ejects blank disk on boot.
