It's a MaxView Phase II CRT I picked up in an auction lot years ago and haven't had the heart to throw out just yet. TBH I don't know what the specs are, but it has the old 9 pin D-sub connector which would seem to indicate it's CGA or EGA.

And yes, I still have the Mac-specific LCD overhead projector panel from the other thread, as well as a mono 640x200 (CGA?) one.

That Infocus panel looks like not a bad buy actually. Note I'm not recommending it for this specific project
