Anothe one exhumed from the crypt, pics went away in the original thread:

MacintoshClassicIIIColorTVp™ Hack

CrapShack had a nifty little Mini-Projector on sale at half price, it was listed as a 640 x 480 unit, but that's the "default setting" I'm not sure if it actually does the 1280 x 1024 (?) resolution or down-converts it to 640 x 480. It doesn't matter though, I intend to run it at 640 x 480 off...

More pics and commentary to add later.

Gonna get back to this one fairly soon, thought I'd post the pics today as they're somewhat relevant to a new project by vorg.

Cool! It will be interesting to see how you and @vorg go with your respective projects.

Awesome project! I'm glad I could inspire you to get it out on the workbench again.

Mine'll be going nowhere very fast just as it's been doing for over twelve years running.

Things of interest for @jorg @vorg project.
-- closeup lenses for short-throw of image
-- pin-cushion distortion induced image correction for field curvature of backside of CRT
-- front surface mirror from (thrifted) overhead projector

Optical unit swings out from the back for ceiling projection through opening in bucket top for gaming

Projector unit only tilts out and back for use as a DVD/5.1 projection TV.

Last page still has intact pics of the 10" Color CRT Classic BenchMac project someone asked about.

@jorg?

I agree on the short throw. It is the development path nowadays with projectors. Those cost $2k or so. Imagine if my SE/30 and SE sitting next to me happens to project on a wall bigger than the 9" screen.

Were you able to make that work yet to project on the wall, @Trash80toG4?

Awesome project! I'm glad I could inspire you to get it out on the workbench again.

Not out on bench, It's been front and center of the AppleDisplayUnit™ for all these years. The pics were snagged off the iFrog album from which they were originally linked. Probably lost a lot of related pics from the upgrade/great pixel robbery and then disappearing cache disasters at the MLA. Sometimes I wish I'd never uploaded directly.

I've never used it as a projector, only for this project so far. Unfortunately it sounds like its powered by turbo-jet. @vorg How quiet is your projector and how much does a cheap one go for these days?

AppleDisplayUnit trademarked? Hmmm. That's new to me.

Only pic I turned up, bad cold, crawling back into bed, but this is the relevant section of the display:
