Apple //c Repairathon!

[Adam]

I’ve been working on a bunch of Apple IIc’s this week. I now have 5/6 working again, and 4/6 have working floppy drives. The last one doesn’t work at all, but gave many parts to the others…

Awesome! What issues did you run into along the way? I'd love to land a IIc eventually. They're such cute machines!

 

[Adam]

Missing/broken keys, lots of bad RAM, a couple dirty floppy drives, some missing/dead chips other than RAM, and one dead internal PSU. I’m outfitting these all with ROM 4X and replacement external PSU’s. I’ve also got a few of the nice little 9” green screens to go with them - those are not so fun to repair.

Doing some testing before these go away!

They look great! Heres my address
IIc is my favorite apple II machine, absolutely stellar design!

 

[Adam]

The first one is ready!

Looks great!

Looks very nice. I'm still looking for a //c monitor to pair with mine.

Great to see so much IIc love! I just got my first ever IIc delivered in the mail today, and I *think* it has bad RAM, although it's hard to say for sure due to ROM v255. Do you have advice on good replacement chips to procure?

I can spare a couple, all tested good with @Stephen s ram liberator device . There are disk programs as well to run diagnostic which pin point which bank etc

I just ordered a batch of dodgy chips from China, but if you have certified good ones to spare I'd happily take you up on that offer! Let me shoot you a private message.

Yesterday a quick googling led to MECC Computer Inspector as a diagnostics program that can help with RAM troubleshooting. However this is what the splash screen looks like when trying to boot it. What are other good options, just in case there's a program small enough to fit in the good memory?
