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...

Desoldering this pesky capacitor would have been a perfect job for low melt solder! I did a similar job this January, and despite buying the special solder only a few months prior, I forgot I had it and went through a similarly painful supercapacitor replacement experience. If the computer is...

I have tried this before, and even if you know what you are doing, it is easy to make things way worse. Keep strong magnets away from crts! :) I think that using a real degaussing coil (either by fixing the internal one or by purchasing an external one) is by far the best way to go.

I'm not sure whether it will apply or not, but here is a potential fix for the no sound issue: I once accidentally plugged my IIgs speaker into a fan header without realizing it. The headers look really similar and I think I remember the speaker making a pop when the power was engaged. The sound...

I just put one of these converters together -it's great, and far more convenient than cramming the Arduino inside the keyboard itself! Using the online QMK configuration tool, I made a custom QMK firmware that allows the F10-12 keys to act as either function keys or volume controls depending on...

I'd love to build one of these boards --does anyone in the US have any spare PCBs that they'd be willing to sell?

This looks really useful and the user interface is neat too! I love the idea of having a significantly more streamlined way to move files around between my classic mac and modern computer.

I think that "too slow" may be (in this case) relative. I have an overclocked 300MHz iBook G3 Clamshell that now runs at 400MHz. I use it with OS9 and 10.4 Tiger. To me, overclocking the computer made a pretty big jump in the computer's speed and usability. It even meant the difference between...

I can't remember where I saw it, but I think it is possible to rig up a power bank to connect directly to the charger port of a PowerBook and effectively act as a portable power brick. This would be easier to implement than designing a new internal battery, but it would be much less sleek.

Cool! It wouldn't surprise me if the modem on the iBook Clamshell is really similar to the Pismo, so maybe this could potentially work for several contemporary machines if we're lucky?

Really cool! One of these plus a SCSI card would make a pretty good bridge machine. I assume this replaces the modem module itself? Any chance it could fit into an iBook Clamshell? It seems like most of the circuit PCB is empty, so maybe further miniaturization would be possible. Are the plans...

The startup circuit in this computer needs a higher voltage than just one battery provides, so there are two. It's okay to just snip the battery legs, and pull them out of the computer that way. They can be replaced with either CR2032 batteries or 1/2 AA batteries. A battery holder can be...

Have you seen this thread? https://68kmla.org/bb/index.php?threads/upgrading-ibook-clamshell-display.38727/ It covers replacing the CCFL Backlight in an iBook Clamshell with an LED strip. Internally, I would expect the Pismo LCD to be quite similar to the Clamshell LCD, so I think that most of...
