| Apple Color Monitor M1212 Cleanup | |
| Posted by: Iesca on 2024-05-07 18:58:24 Roommate brought home an M1212 from his place of work that was gonna be tossed, but boy is it in rough shape. Filthy, with a cracked bezel and a missing stand, just to start. After managing to pry off the back of the chassis I blew it out with an air compressor and shook it out. It clearly spent some time in the outdoors, and a rodent of some kind made it a home at least for awhile; plenty of feces came right out, in addition to a couple of acorns and tree litter that were hiding in there. Despite all of that, the board appears to be in reasonable shape, save for a chewed up wire and the rubber cap at the base of the flyback. Going to try and get it cleaned more thoroughly with bleach and wipe everything down, just to make sure it's safe to handle. Replacing the caps and that wire should be easy enough. I have of course not turned it on or even plugged it in. However dirty it appears in these pictures, it was assuredly much worse before wiping it down with window cleaner... Those two metal tines, I'm thinking they were from the stand, as I don't see them in the blow-up diagram at the end of the M1212 Service Source. | |

| Posted by: Iesca on 2024-05-08 14:59:20 @LaPorta PM'd! @robin-fo We'll see what happens! Just finished dismantling it last night and showering out the shell... | |
| Posted by: slipperygrey on 2024-05-09 21:47:03 Love the M1212. I’m rooting for it. 🙂 Some time ago I compiled a cap list for the boards over at TD, if you ever need a reference. 
Macintosh Color Display M1212 Capacitor List (1-645-346-13)While working on refurbishing a Macintosh Color Display M1212, I took the opportunity to record the electrolytic capacitors on the "analog board". There didn't seem to be any electrolytics on the neckboard. Location Capacitance (μF) Voltage...

| Posted by: iantm on 2026-07-16 15:33:45 I just acquired an M1212 — without a stand. Anyone found a solution that works for a replacement? I’m pondering a PETG hack stand or TPU feet made to stabilize. Or maybe it won’t be as bad as I think without it, just not able to swivel? | |
| Posted by: Iesca on 2026-07-16 15:56:15 It was pretty common to not have a stand since it was sold separately. The monitor would just be positioned on top of the machine, or someplace convenient. That said, it would be nice if someone were to make a 3d printable version of the universal stand, as the ones that are out there are exorbitantly expensive. | |
| Posted by: iantm on 2026-07-16 15:57:51 Oh, I didn’t know it was separate. I assumed it was just lost or broken. So maybe this will be fine without it. But I still might explore making one. | |

So yours must have lost it... | |
| Posted by: iantm on 2026-07-17 06:39:01 Ah. I wondered. It seemed rather permanent. I'll see what I can do to make it work… | |
| Posted by: Iesca on 2026-07-17 09:49:41 Ah, I was thinking of the older model, my mistake! | |
| Posted by: iantm on 2026-07-17 10:33:40 No worries. I’m sure I can figure some way to make it work. Too bad the “universal” monitor stand doesn’t work at all. | |
