I recently overclocked my Clamshell's CPU to run at 400MHz (and the bus at 100MHz), and the ~20% speed boost means it's now barely fast enough to use on a few parts of the internet. I had to take a picture of it displaying this same thread on the 68kMLA forum. :) The backlight modifications I...

I would try to take the Clamshell apart to the point where you can inspect the hinge mechanisms underneath the top case. I think it could maybe get jammed if the "clutch cover" plastic section between the hinges was improperly aligned at some point. At the very least, taking the top of the...

I think I ran it (along with A2Server) on a Raspberry Pi model B once --I don't remember having any issues that were the Pi's fault.

This is pretty cool! I'm a bit confused what the purpose of using a IIci rom in a IIsi would be, though. What advantages does the IIsi have over a IIci? As best I can tell (at least from some preliminary Wikipedia-ing) , the IIci looks better than the IIsi in every way. Would basing this...

I'm glad this information was useful! Thank for the 3D model --that looks like a very nice solution (I bet that it's much more repeatable for others compared to toothpicks). I've discovered a minor flickering problem with the backlight controller modifications I detailed in the previous post...

I've not looked into this, but I would bet it's possible to flash the GPU ROM with an inexpensive CH341A clip-on USB programmer if you don't have a period-accurate PC lying around. (I recycled all of mine to make more room for Macs!)...

I don't think that this is an XFX 6200. From what I have seen online, those models have a black-colored PCB and a green DVI port. I have also seen a PCI variant that has a blue PCB, but it wouldn't be compatible with a G4 Cube. I wonder if this particular GPU was an NVIDIA instead of one that...

There are also models for the GeForce 6200 --https://www.thingiverse.com/thing:4659096

Awesome --I hope you can get this working! This is something I dreamed about several years ago when the first reverse engineered schematics were being created. I think that OpenBoardView would be super useful for troubleshooting work: instead of needing to look over schematics to find where a...

I just found this on eBay while searching for a Radeon 7500, which doesn't seem to be available in a Mac variant: https://www.ebay.com/itm/251126702780?hash=item3a785162bc:g:F3UAAOSwh1haBsn4 It's a Radeon 7000 that is supposedly G4 Cube compatible for $25 shipped. I don't love that its...

The display's brightness control is now (mostly) working! I bodged the controller board to match the alternative schematics that I found in the control chip's documentation. I needed to reverse-engineer the driver board by desoldering several components, placing the tiny PCB on my scanner, and...

I think I figured out why the brightness control isn't working! I took my iBook apart again and used an oscilloscope to analyze the signals on each of the backlight wire's pins. I expected to see some sort of changing signal when the backlight is adjusted, but it turns out that the only thing...

Thanks for the tips! I threw another 4MB of RAM into my SE/30, and the performance became noticeably better. The game no longer crashes after the first few seconds, and it runs more smoothly. I can tell now that each time the drive seek light turns on, the music stutters, so I think running the...

I saw this video about building an Apple 1 replica a few months ago: The gist of it was that you can assemble a pretty realistic-looking replica however it is a challenge to find original (and long-since discontinued parts). The obscure computer chips that the Apple 1 used means this project...

I finally got around to doing this project! I am using a Radius Color Pivot IIsi video card which doesn't fit inside the SE/30, but I was able to hack something together outside the machine, and it works! I don't think that I will be able to connect this model of video card to my AppleColor...

I have replaced some of my computer's clock batteries with CR2032 coin-cell batteries. I have never seen this variety of batteries have problems with leaking before, and I couldn't find any evidence of them leaking online either. They are way cheaper than the 1/2 AA batteries that these...

Apart from the burned connector, I think that this SE/30 looks like it is in really fantastic shape. @JDW made a video a while ago where he repaired a Macintosh SE/30 analog board with a similar problem; perhaps it could be of some use to you (fast forward to about 5:30 in the video for this):

I love how bright the screen gets now. :) Brightness controls kind of work, but they are the one issue I am still working on. The screen just doesn't get dim enough at the low settings for my liking, and the brightness controls are inverted so that max brightness on the computer is minimum...

It's alive!!! :) 
 I finally replaced the backlight on my iBook Clamshell with an LED module. This upgrade makes a massive difference in overall usability for me, as I no longer need to strain my eyes to read what is onscreen. Now, everything is crisp, sharp, and bright. The LEDs are evenly...

Yes! It is pretty much the same solution as connecting an ADB keyboard. It would consist of building the Arduino Pro Micro solution described above, and using an S-Video-style ADB socket (for the mouse to plug into) rather than installing an Arduino directly into a keyboard. Whoops! I read your...
