Here's an update on my Mac II. Someone from a local Apple society had a spare monitor cable.

I plugged it in and my Mac II runs like a charm.

(And I did not have to replace either of the batteries.)

I forgot how much good stuff I ran on this machine - Word, Quark, PageMaker, MacDraw, FreeHand and even a couple games. Not to mention all the little apps I gathered.

Thank you all for your suggestions. I likely would have gone through some major hair pulling with soldering batteries, buying a video card and other nonsense thinking the motherboard was bad when all I needed was the right monitor cable.
