Is the ROM-Inator just comprised of those two SMD chips in the very center of the logic board? Great work on this project! I can't wait to see the prototype PCBs. :)

Unfortunately, this Classic Logic Board has been very badly damaged by battery leakage. I think that it is beyond saving, as many of the traces/VIAs connected to the CPU are damaged. The good news is that there is a project underway to make reproduction Classic Logic Boards. If you save this...

When you recapped the board, was there a lot of electrolytic goo underneath the original capacitors? If so, did you make certain to remove absolutely all of it from the analog board? When I fixed my Classic, the analog board was practically dripping with leaked electrolyte, and I had to take a...

I think this is a fantastic reason why the dishwasher method should be avoided. Presumably, similar results could be achieved in a utility sink using a high-pressure stream of water through a hose anyway. (In a pinch, I'd bet that my garden hose set to "Jet" would certainly blast lots of dirt...

A few months ago, I did a complete teardown and reassembly of a 12" PowerBook G4 from 2003. There were tons and tons of screws to keep track of, but their quantity was far from the worst part. The spring screws that held the heatsink to the motherboard were connected to some flimsy nuts on the...

I would take a look at this video: I think that it should contain the information you'll need to run the backlight on a TV/monitor LCD panel without providing a video signal.

Here is a scan showing the split power planes from the top of the logic board. This picture shows where the power plane splits on the bottom of the logic board. (Please excuse the uneven sanding in this photograph --I eventually figured out how to sand more evenly, but this is one of the only...

I worked with @Kai Robinson to sand through the classic logic board layers, and I took scans of all the inner layers a few months ago. All of the related posts were lost in the 68kmla crash, but I still have the scans if you need them for this project.

You should be able to try using a cheap voltage boost converter to get the necessary voltages for powering an ADC LCD. I think ADC runs off 28VDC, so you probably can just boost the 12V rail to make this work. Something like...

The prices seem to have increased for Power Supplies as well. I bought a new SE/30 PSU for all of $9 about three years ago --they are closer to 5x that price today. 😕 I guess that's the nature of eBay! I think that this flyback transformer definitely needs to be replaced. If you are interested...

Here is a copy of a forum thread I started a few months ago. @jeremywork had the tab open when the forum crashed and he was kind enough to rescue the HTML files and send them to me. Please note that none of my post's photographs were preserved in the download. If anyone would still like to see...

I also think that the issue you have described is indicative of a short. I would recommend systematically unplugging everything from the motherboard, seeing if the PSU turns on with only the motherboard connected, and then adding peripherals one by one. Once, I bought a faulty DVI to VGA adapter...

My first post on the post-crash forum software: Thank you for writing about your G5! This post was interesting to see. I'll have to take a look at my G5's CPU cards one of these days. I hope that the capacitors aren't all leaky yet, but I do love a good recapping project anyway. :) As @demik...

I think the idea of resin is to stop the irregularly-shaped logic board from wobbling around, or from being anything but perfectly level as the milling machine slowly removes each layer. Honestly, with every component removed from the board (thus making it flat), this may not be necessary. As...

What looks exciting to me is that you can use the Catalina Patcher on this model of iMac to install Mac OS Catalina. Big Sur might also be possible with a bit more work. In terms of maxing the computer out, I think you should opt for an SSD drive over anything else, even if its an $18 256GB...

The good news is that you can practice this procedure on a really cheap thrift store monitor before trying it on a nice Apple ADC one. I have considered trying to replace the CCFL backlight inside my iBook Clamshell with an LED one, but I am holding out until it becomes absolutely unusable, just...

Sugru probably won't work very well because it is still soft when it cures. I think you'd be better off filling the hole with epoxy and retapping the threads inside.

It looks to me like all of the capacitors on your accelerator are tantalum capacitors. They are probably still fine, as there is no fluid inside them. From what I have heard though, when tantalum capacitors do fail, it is usually spectacularly (in a puff of smoke). Maybe replacing them...

I think this motherboard looks like it is still in pretty good overall shape, especially considering the battery leaked. If you think it looks really bad, take a look at this picture of my Classic from a few years ago:   There do seem to be a few problematic spots on your motherboard that...

I think the link is broken, do you mind re-posting it?
