Thanks for the welcome and the advice!
Oh hey, bigmessowires -- I remember stumbling across your website quite some time ago.. Was quite impressed with your FPGA Mac Plus.
I've read about this bleeder resistor, though old habits die hard.. With my luck, I'd start messing around in there and find out that they'd forgotten to install it. I cut my teeth recapping dangerous old Electrohome G07 arcade monitors, so I'm quite familiar with the screwdriver-under-the-suction-cup technique. Though after frustrating myself with piles of corrupt floppies getting a fresh system installed, I didn't have the nerve to start shorting things out.
Brooklyn.. Thanks for the link. That'll be a big help in getting the analog board out, though it doesn't seem to delve into any kind of board-level diagnostic..
Sadmanonatrain.. I'll fiddle with that setting and see if it helps things at all. I have a feeling there's something else wrong here, though. The fact that the Mac is telling me that the Brightness control panel can't even be used on this model suggests something's amiss.
How does this computer-controlled brightness work? Is there a special monitor sense line that tells the mac that it is in fact connected to an internal monitor and that is should be controlling the brightness? Should I pop over to the LC forums and see if this problem ever occurs with 500-series machines? (That last question is rhetorical, I'm doing that as soon as I submit this post.)
Thanks everyone!
