I'm trying to revive my Powerbook 100, and would love some help advice. Here's the specs: Powerbook 100 4MB Ram, 40MB HD, 16 mhz, external floppy drive. The last time I started it up I got the flashing question mark inside the floppy icon. Remembering this, but not having my OS disks, I downloaded a copy of System 6.0.1L and put it on a floppy, but when I pulled the powerbook out and turned it on here's what happened: I get the Apple chime, which I figure is always a good sign. And it sounds like the harddrive is spinning up and the processor is processing...but the screen does not come up the way I expected. It's definitely on, but dark in the center with a 1/4 inch perimeter that glows blue/gray. Adjusting the contrast and brightness do nothing, do not affect the appearance at all. When I pop the OS floppy it, the floppy drive spins up like it is reading it, then spits it back out. So, I'm thinking it's one or more of the following: 1. Screen is bad or some connection to it is bad. 2. Graphics chip/card/processor whatever it is in these, is bad or some connection to it is bad. 3. The OS floppy I made didn't work. 4. The PRAM batteries are dead. 5. The whole thing is fried, though if that were the case would I still get the chime? Any advice on things to try, take apart, diagnose is most appreciated. BTW: My current computer is a 13" MBP, running Snow Leopard, I borrowed an USB floppy drive, thats what I used to make my System 6 floppy. I don't have access to another pre-OSX machine. Thanks in advance.
