I tried that by attaching a patch wire between Pin 24 and the ground pin, and the CRTL was stuck on while the wire was on. Desoldered it from ground, and the CRTL key wasn't stuck anymore... only for it to go back a few seconds later. It seems like it's totally random if it works for a moment or...

Well, I tried to use it again today and it's holding the CRTL key again, but this time it's weirder.  After about 5 seconds of it being plugged in, the key will start to jitter on and off and eventually settle on being on. Now, if you ground Pin 24 (P23, I/O Port 2) the problem will be fixed for...

I took kind of a weird approach and decided to use a USB SD card reader with my Power Macintosh G3 tower. With that, I could take my SD card out of my LC II's SCSI2SD, plug it into the SD card reader, and transfer files from there. I like MrGasS27's idea of using MacDrive though, never heard of...

I thought that maybe something was wrong with the microcontroller, so I started poking around it with my multimeter to see if the pin out for its NEC 80C49 (AEK1 controller) and the Toshiba 80C49 (AEK2 controller) were the same so I could do a replacement, and... the problem went away. I think I...

I'd go with what Rickrob said - $10 for a full set of capacitors is a good price. I didn't know about that when recapping my LC II though, so what I did was I went on Mouser and bought high quality low ESR caps from Nichicon that matched the exact values of the original caps. That's worked well...

I hadn't really put much thought into the corrosion because I didn't see any obvious corroded or damaged traces, just damage to the very outside of the board. If I need to repair traces, what would you say is the best way to go about that? It's a bit out of my area of expertise since I've never...

Got the G3. Very cool machine, but unfortunately I've figured out that the AEK is at fault. When I initially plugged the keyboard into my G3 though it didn't instantly turn the Control keys on, it only happened after pressing Scroll Lock. I'm going to see if I can figure out what conditions the...

I couldn't figure out how to take the switches out after desoldering, but I did get both of them desoldered and I took them completely apart and prevented them from making any contact with the logic board. After unplugging and plugging the keyboard back in a few times, the Control key eventually...

Yeah, my AEK uses ALPS Orange. Very very nice to type on. I'll try what you suggest later today and see what happens - the good news is that if it is the key switch, it's only $5 on eBay for a replacement switch.

I just poked around again and I can't find anything that could be wrong. Just for curiosities sake, I tried booting the LC II with only the mouse connected and going into KeyCaps, and neither Control key showed up as activated. As soon as I put the AEK in though, they showed up as being pressed...

I couldn't find anything on it myself. I took a photo of it, can't seem to get one that's super clean, but maybe you'll see something that I don't? https://imgur.com/pvGASyf

Just took apart the other Control key cap, no luck with that either. I don't know what part on the keyboard is causing an issue, if it even a part on the keyboard. I might pick up a PowerMac G3 Biege soon that comes with an AppleDesign Keyboard, so if I get that then I'll try it with my LC II...

I've never had it enabled, but I checked just in case something happened. Nope, not enabled.

Welp, I messed with it again and managed to fix the issue for a split second, but upon pressing CRTL again it reappeared. I have no idea why it could be activating, I even have the switch completely taken apart. I'll poke around more tomorrow.

I just took a look at KeyCaps and you're right, it looks like both of the control keys are being held down. Hm... EDIT: I just tried to reflow the solder on the control keys. No dice.

I don't know if this exactly goes into peripherals since I'm not 100% sure the AEK is the cause of the problem here but I dunno where else to put it. I finally got my LC II up and running with the aide of a SCSI2SD, and it's working great! Except for text entry fields. Everytime I type something...

Well, I tried some things. Disconnecting the HDD didn't make it boot any faster, but it did boot without it. I tried opening it since I thought the cause of death might have been sticky rubber, but as it turns out the cause of death is even weirder: shattered glass? It was originally...

Hi Mos, I recapped the PSU - was actually the first thing I did. I'll disconnect the HDD tomorrow. I did try a floppy boot a moment ago - the system recognizes floppies and will try to boot from them. Unfortunately all my floppies and floppy drives are acting up so I wasn't able to write a...

Hey all, I found out about this site when trying to figure out how to repair an LC II. I recently got one for free off of Craigslist - it was really dirty and didn't boot. I ended up recapping the entire system, which now made it finally start but there's two quirks. 1: The system takes a long...
