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.

Great work! When I get a chance this week, I hope to do a similar mod to a PowerBook G4's LCD.

If you just want internal color, wouldn't it be a lot cheaper and easier to use another more plentiful video card, like the IIsi PDS card (the $10 one that needs to be cut with a saw)? I'm not sure I see the advantage to using this expensive custom greyscale card if its greyscale capabilities...

You were right --here is my PowerBook 1400cs running off of USB-C!

Update: I received the BixPower and 20V USB-PD adapters and connected them to my iBook G3 Clamshell. These work perfectly, and despite the original charger providing 24V, the iBook seems to function correctly with only 20V of power. I am using the 96W power brick that came with my MacBook Pro...

I use this T12 soldering station...

I've been meaning to find a replacement barrel jack for one of these chargers as well. My idea is that theoretically, a custom USB-C PD to Mac charger cable could be made, which would make it a lot easier to find a reliable charger (just plug it into your modern laptop power brick). Also, if...

I didn't use any resistors when I did my mod. I also removed the CCFL driver board entirely, but I don't know if this was the right decision. It looks like your LED driver board differs slightly from mine, but they are based on the DF6113 IC. You mentioned that lower brightness settings made...

Good work! I did something very similar to my iBook clamshell backlight a few years ago, but never quite got the brightness control working perfectly. I'm curious to see what you figure out with the LM1172. https://68kmla.org/bb/index.php?threads/upgrading-ibook-clamshell-display.38727/

I remember having a really hard time finding the right value PRAM capacitor. I believe I just bought one that was roughly near the original value, and it worked fine.

I think you'll need to drastically compress whatever modern images you try loading onto the older computer. I'd imagine Photoshop 1.0 will struggle with anything bigger than maybe a few hundred kilobytes in size. Each photo I take on my phone is about 25MB for comparison. From what I remember...

Do you have a multimeter with a continuity test feature? You can verify that this trace isn't broken by testing it with multimeter probes touching from one end of the trace to the other side. It is also possible to get dust inside the mechanical keyboard switches, so I'd also try cleaning them...

Interesting! I never realized m.2 sata and mSATA we're different technologies. I just checked the m.2 sata prices, and they seem pretty reasonable, so I'll have to give it a try when I need a new IDE SSD.

Coincidentally, I've been playing with the exact same LCD panel recently. On eBay, it cost me about $37 USD shipped from China, so it was a pretty good deal. I think that the screen's IPS panel looks very good, especially for the money. Even though the resolution is relatively low, it works out...

Generally, I've read it's best to have an oscilloscope with a rating at least 5x faster than what you'll need it for. This means that the 20MHz 6022BE would only really be useful for computers up to 4MHz. Similarly, if you get an oscilloscope that's rated for 100MHz max bandwidth, then you can...

Have you confirmed that this new oscilloscope is working and will show any waveforms? Perhaps you should try probing a logic board from a compact Mac (specifically its oscillator crystal) just to make sure that the measurements you are taking from the Apple III are valid. Is this the model you...

It's amazing (and frustrating) that scan times haven't seemed to improve with more modern scanners. It takes my scanner (a fairly nice and modern Epson v600?) so long to initialize and respond to commands compared to the actual scanning time. There are some faster auto-feed scanners now that...
