My experience is that the LC 5xx (and Color Classic) need FPM. Interestingly, while the Apple Developer Note for the 575 says that modules need to be 80ns or faster, it doesn't offer much else in terms of specifications beyond mechanical drawings and pin assignments. The 575 service manual...

I'll echo the sentiment to not overextend yourself, but also offer the suggestion to reconsider your video style or workflow to make episodes quicker or easier to produce. For example, instead of primarily doing pieces to camera (which, as you've said, you have to shoot at work due to noise...

Several years ago I bought a Hioki DT4252 and haven't regretted it. It's made in Japan (with build quality to match) and has a solid feature set. Hioki isn't a big name outside of Asia, but from what I've seen they have a very solid reputation. The price has gone up a bit over the years; it...

What's funny is that while the final production eMates only came in green, the replacement styli (like @ScutBoy has) came in the same colors as the prototypes. I have an orange replacement stylus for mine that's the same shade as in the above photo.

IIRC pretty much all of the parts are interchangeable between the 520 and 540 models. The service manual lists a "540c Upgrade" kit that was sold (page 168 in the PDF), which would replace a 520/520c/540's screen with the active-matrix panel from the 540c. It's possible that the display ribbon...

My two cents is that the very inexpensive printers aren't a good idea for people who are new to 3D printing. They seem to be fussy and require some knowledge to get working properly. If you can expand your budget, the Prusa Mini for $349 (or $399 fully assembled) is an excellent way to get into...

I've used Kapton successfully many times as a way to protect SMD components from accidentally getting desoldered when I'm doing rework. However, that's usually when I'm putting the replacement components in place, in case I slip with the soldering iron. For hot air work I'll use pieces of...

From your photo, it looks like the E, R, T, S and V keys are the worn ones. Thankfully these keys are in the same positions in other keyboard layouts, including North America, so you might be able to get away with just getting replacement keycaps -- the donor doesn't have to be a French one.

As promised, here's my video about replacement brackets for the 1400's CD-ROM drive bezel: The .STL files are available here: Thingiverse, https://www.thingiverse.com/thing:5176310 PrusaPrinters, https://www.prusaprinters.org/prints/106933-powerbook-1400-cd-rom-drive-bezel-brackets

I'm not seeing them either. I went through my archives of service manuals and found several for Power Computing machines. They're separated by model (PowerBase, PowerCenter, etc) and form factor (desktop or minitower).

Yep, I'd be in for a spool or two as well.

So you may know that I have a soft spot for the Color Classic -- it's my favorite desktop Mac. And while I own two of them, the original Color Classic wasn't the only model that came in the form factor. I've always wanted a Color Classic II, for no other reason, really, than for the sake of my...

I haven't swapped the drive in my Cube yet, but based on my recent experience installing an IDE-to-mSATA adapter in my 12" PowerBook G4 with a 128GB module, I'm certainly thinking that'll be the way I go.

I tried both of those files, but they just extract to .cpt files. Not sure what to do with them? This is getting me closer. After going through StuffIt Expander Hell (forgot I didn't have both older and newer versions on my SheepShaver disk) and patching the program, it's indeed giving me the...

It's perhaps no secret that I'm a huge fan of SimCity 2000. I remember long ago having a cheat patch that could be applied to the application that maxed out your budget to something like $10 million, and also unlocked *everything*. This was *not* the porntipsguzzardo cheat code, it was...

I printed them with PLA, but you could use whatever material you prefer. I've had good luck gluing PLA parts using CA glue meant for plastics.

There are a *lot* of SMD caps inside these machines, but thankfully, there are only two kinds. Here's the breakdown: Logic board 23x 47uf 16V 3x 33uf 25V PCI riser/graphics card 8x 47uf 16V CPU card 1x 47uf 16V The attached photos show where and which ones they are. (Sorry that they aren't...

Got the brackets modeled and printed. They fit in the drive itself, but I haven't glued them to the bezel yet. I'm planning on making a short video about these and another PowerBook-related 3D printing project, but here's a teaser.

It would have been either Apple or Quanta who designed the bezel. The 1400 was an interesting machine in that the chassis was actually a "whitebox" design from Quanta. In order to get the machine to market faster (and bypass internal dysfunction), Apple basically gave the motherboard schematics...

I've got two PB1400 CD-ROM drives this has happened to, and on my to-do list is designing some 3D-printable replacement brackets that can be glued to the original bezel. It's crazy (though not surprising, given the era) that Apple used such small/flimsy brackets, though I suppose the drive...
