I just took my old LED driver board mod apart and reconfigured it to match the plans posted by @AEChadwick. So far, so good! It all seems to be working perfectly --much better than the previous mod revision, with seemingly none of the old drawbacks. A big thank you to @AEChadwick for sharing all...

This is excellent! I haven't given this new version of the mod a shot yet because my iBook is still recovering from a partially finished XGA mod. BTW, I saw your post on another forum about the fully upgraded iBook you've built and I'm very impressed! I hope to get my clamshell to a similar...

Fantastic! I look forward to trying this out!

Great work! I'll have to play around with this at some point! Two questions: Does this version of the mod fix the issue where the brightness gets sort of "jumpy" as you go between the levels? I remember my mod idea from 2021 wasn't perfect because the brightness would sometimes increase even...

I foolishly tried this in August without shaking the can of Brasso first, and it ended poorly. Very thin oil poured out of the can and immediately seeped inside the LCD panel and click wheel of my iPod. The moral of the story: mix the Brasso and pour it onto a rag first, not directly onto the...

Are you trying to run a modern speed test like speedtest.net? There is a ton of overhead in actually running the javascript and everything else online, so it wouldn't surprise me if the problem is that the G4 is struggling to cope with overhead, rather than actually having slow ethernet. The...

In the picture you posted, it doesn't look like the DC-in board is fully seated in its connector on the logic board. Did you eventually plug it in the rest of the way? The issue could very well be the power brick as well. I once had a power brick with a mangled connector, and this was nearly...

Great work! Another Macintosh Classic is back in working order. I'll have to try putting together one of these replica boards together once more are manufactured!

Here's another possible solution: let the mouse sit untouched for a couple of years. Some of my earlier retrobrite disasters (and successes) seem to have reverted to their prior condition after sitting for about six years in storage.

Where did you find this? Are they still available for sale somewhere? I've been thinking about doing a similar job to my battery-damaged classic board. I tried the same serial diagnostic that you did, but I couldn't get it to work either. My Classic must be too far gone. I think it might be...

I think I know which piece you are referring to now: https://www.amazon.com/USB-C-2-5mm-Emulator-Trigger-Laptop/dp/B07P81526M

I used a standard USB-C to USB-C cable, the same one I use to charge my Google Pixel phone.

Have you confirmed the serial adapter works with another computer? I think you can use a program called Zterm on a vintage Mac to test this. Another program that I used a couple of years back is called MicroPhone (I can't remember, but this one might be better than Zterm?). You should be able to...

Bummer about the wrong pinout serial cable. For the USB-serial adapter, I had success using a standard DB9 adapter with a second DB9 to DIN cable connected between it and the Macintosh. Something like this: https://www.amazon.com/PCCables-com-Female-Mini-8-pin-Male/dp/B00ALULFX0...

Great work bringing the power supply and analog board back to life! While the computer still isn't booting, we now know most of the main components are working. You should be able to use any modern computer and a USB to serial adapter. Something like a Unix/Linux terminal, ZTERM, or PuTTY...

This sounds like it might be a RAM issue to me. My theory is that OS9 likely uses more RAM than OS8, so it doesn't exhibit symptoms under OS8. I wonder what happens if you saturate the RAM when running OS8. Does it crash? I'd try replacing the RAM stick and see what happens.

Good work on the battery-damaged logic board! I did something to a similar PCB a few years ago, and almost got it working again. (You've reminded me I should dig it out and play with it again :).) From your photos, it looks to me like there's a considerable amount of capacitor leakage on the...

I've done overclocking to my clamshell. The improved performance results were absolutely worth it for me. You should be comfortable soldering resistors that small, but otherwise, as long as you start with a light overclock, and build up from there, I think the risks aren't terribly high. I did...

If you unplug both the SSD and the CD-ROM drive, you should still expect to see a blinking system folder with a question mark. If this doesn't show up, something else must be wrong with the iBook. If Open Firmware isn't loading, this seems like it may be a more significant issue than just the...

Is the display's video connector fully seated? If only the backlight were plugged in, you'd see a blank white screen, but nothing more.
