No dice - all I get with the LC575 flyback is a light crying noise from somewhere, kinda sounds like an SMPS being overloaded. Oh well, it was worth a shot and now is documented for others to google!

I'll do my due diligence and try to trace the rest of the M1212 circuit to make sure it matches the LC575, but my gut feeling is it'll "just work". I do believe the color classic is very similar but probably has some small circuit changes for the different tube size and horizontal frequency...

I had a quick peek at the LC575 horizontal section comparing it against the M1212, so far it looks identical, even the component designators are the same. With the same video timings and CRT I wouldn't be surprised if it was a copy/paste with some components rearranged to fit. The yoke is the...

Understood, I was hoping since the CRT was the same part no. on both displays, the filament, screen and anode voltages would be the same. Hard to say for sure of course. Design looks very similar between the 2 chassis. Focus and screen pots are located on the monitor PCB here.

That's the hope, my M1212 is in nice shape aside from the flyback, I'd like to pull the flyback out of my parts LC575 and install it into the M1212. The only thing giving me pause is the part numbers are different. Just curious if anyone here has attempted this swap before. Getting a donor...

Hello hivemind! I'm working on getting a M1212 monitor fixed up - seems to work well except that the flyback transformer makes a god awful screech. I want so badly to use it with my Quadra 605 but I can't stand being in the same room... I've tried coating parts of the flyback in RTV to dampen...

Thanks! Will do. I went ahead and picked up an external 400k drive that I plan on migrating to the 128k so I can get it up and running, then I can take my time and dink around with the bad one

I think if I need to ask, I probably know the answer, but I want to make sure. This 400k floppy drive had the following issues: The drive was stuck in the down position The felt pad was missing from the pressure arm The head looks like this: From these clues, I'm guessing someone tried...

Hey all! I'm looking at picking up a Macintosh Plus (RAM upgraded to 4Mb), and have absolutely no experience with these older machines. Just wanted to ask a couple questions to those that are familiar with them: I won't have an external disk drive to go with it (may go the scsi2sd or Floppy...

I installed the Pioneer drivers and it's now reading disks. You guys rock! Unfortunately the tray sits a bit too high and isn't lined up with the slot in the Performa case, so I'll just have to use it in the external enclosure for now. Thanks again for the help! I was able to use the drivers...

Huh, interesting! The unit is a Pioneer DR-US124X. I thought it was a bit weird that there was no apple branding on it whatsoever. Now that you say this, I'm almost certain it was a replacement. I noticed that the ID select on the back of the external drive did not match up with the ID listed by...

Thanks for the ideas! For some reason I hadn't thought of taking the drive out of the enclosure and putting in the computer, duh! I tried it but unfortunately it acted basically the same as it did before. I got it to appear on the SCSI bus, but it couldn't read anything. I tried it on the same...

Hi guys! I'm a noob, tried a bit of googling and searching without much luck. Apologies if there's already a thread that solves my issue! I recently got a performa 577 with a bad internal CD drive, I was also given an external AppleCD 600e that I wanted to try to hook up so I could play larger...
