Interesting. I’ve never seen any other reports of this failure mode, so I was hoping it pointed to something. If there were still bad memory, I suspect I would see some corruption in the characters (I’ll try putting some of the questionable memory in to see how the machine responds). Anyway...

Looking for some guidance as someone who was a Mac user as a kid, but not Apple II. I picked up an Apple II a few years back, and didn’t realize until after I bought it that it was actually a clone. When I first got it, I had issues with garbage on the video output and traced it down to what I...

Just a note I got 2 machines from him and not ended up working. Neither booted initially, but it's because they will not boot without RAM. Cleaned them when I got home and added RAM and both booted, with a good amount of crackling sounds from the analog board / flyback. I gave them both a...

Is yours missing? Broken? I had the key cap's stem break on my caps lock key and was able to 3d print a new one. Obviously not helpful if your key is completely gone, but if it's simply broken, the new stem should get it fixed right up.

Interesting. I tried in both the original .dc format as well as using BMOW's utility to convert to .dsk. I have a model C as well and have used it for other Lisa disk images that came on the BMOW SD card. Update, I tried again with the .dc files and realized that the issue was that it appears...

Are the .dc disk images just disk copy 4.2 images? I've been trying to get them working with my FloppyEmu and it does not seem to like them. I tried copying them to my MDD running 9.2.2 and using DiskCopy 6 to open them and they fail to even open the disk images. I tried to convert them to the...

Thanks for the confirmation. Yeah, there was some less than ideal angles when trying to solder on the new SMD caps, but I managed. I pulled pretty hard, and even tried some medium prying with a plastic spudger tool, nut didn't want to risk breaking anything, as 20" G4s are pretty hard to...

So, I couldn't figure out how to do it, so just went cave-man and replaced the capacitors with the thing hanging off the bottom of my iMac's base. Would still love to have an answer from someone who's removed it. It does appear to be the cable that runs to the display. Also, thoughts on...

Trying to recap my iMac G4 20” and I’ve run across a connector I cannot seem to remove. On the 17” iMacs there is a similar connector with a plastic cap over it that seems to be intended to lock the connection in place. This one looks like it might be similar, but I’ve tried prying and sliding...

Unfortunately I think that is the one variant Androda doesn't make. Might be worth reaching out and seeing if he would be willing to add it to his flex cable recreations. https://androda.work/product-category/macportable/

I also had an issue with it not being able to boot the PC that re-seating the CPU and applying new thermal paste resolved.

I had a few extra coiled ADB cables. I cut off one connector, figured out which wire went to which pin, and connected them to a connector. I think I discussed it in this thread, but the 1st connector is 2.0mm pitch, not 2.54. But that allowed me to swap cables and made it easier to paint the...

Good timing on this post! It gave me the motivation to fix the sound on an SE/30 I picked up recently. My symptoms were no sound through speaker or headphone jack, but also the machine would partially hang when trying to play certain sounds in the control panel. I forget which sounds, but I...

Here's the 5 I made (5 PCB minimum order, why not spend a ton on key switches, and key caps?!?). 4 of the 5 are functional, and the 5th is waiting to find another ADK that has the ALPS controller in it. I really like the black case, with dark keycaps from keychain...

I believe no PRAM battery is better than a dead PRAM. I don't believe the 5500 requires a PRAM battery to boot (at least mine doesn't). However, the symptoms feel like a dying power supply. Sending wrong/fluctuating voltages to the analog board might explain the enlarging of the image during...

True, but the coin cells go dead pretty quickly, and the Mac II seems to be pretty sensitive to power. I also don't want to have to remove the floppy / HD tray to access it when they need changed. I have a non-working Mac II that I did replace with AAA battery holders and I attached them via...

Awesome information. I saw it was an Apple part, but apparently not too many people opted to install it based on online image searches. I'll likely remove it and replace it with a battery holder and wires to get the batteries away from the logic board.

I picked up a Mac II recently and was looking to do a recap. However, the board markings show a number different than what I can find reference to online. It seems to be very similar to pictures I've found of the 820-0163-02 board in terms of capacitor location. One difference I did...

Yeah, I had a dead Cube PSU and I replaced it with an older 27v mean well PSU. I did have to 3d print a piece to extend the length of the case. However, I think newer PSUs may be able small enough to fully fit into the original case. Definitely something to keep in mind if the recap goes poorly.

I'd throw some batteries in there. Most likely either the base is bad and not supplying power to the unit, or the DC adapter is bad, given that neither work. I have a PowerCD that is broken on the bottom. Any chance you'd be willing to sell one of your units?
