  1. Okay! So I can confirm it is definitely the 410-1308 screws. My hardware store didn't have a 5.8mm long M3 screw (not terribly surprised) so I picked up some 5mm and 6mm screws. I tried the 6mm first, and it fits like a glove. So the screws you want are M3x6mm with a 0.50mm (coarse) pitch. I got ones that are pan head Philips, and they look just fine installed.
  2. I really wish we had replacement injection-moulded cases for the 520/550/575. 'Just went to investigate this and broke the only non-broken clip on the I/O cover. Anyway, my 550 is missing those screws, so I haven't confirmed this yet, but let's see what we can figure out. According to the Macintosh Computers Service Guide, Volume III (July 1994), page 108, there's two screw sizes used for the rear housing, but no indication of which one is used for what. (Not even how many of each one is used.) One is part number 426-1007, which a cursory Google search seems to indicat
  3. It is indeed Stanford. Here's the page on how to access the archive: https://library.stanford.edu/areas/apple-computer-collections/access-apple-collections
  4. I have a 47.8MB TIFF (3800x4080px) of a decapped IWM, as well as a bunch of technical information (schematics, specs, engineering drawings, etc.). Do you already have these? IWM_Info.zip
  5. Oh come on, don't leave us hanging like that!
  6. For what it's worth, the battery on those clamshells just uses six standard 18650 lithium cells. Very easily attainable and a pretty simple job to install into your existing battery pack.
  7. I just recently came across this, too. I'm curious because it says that it specifically emulates an AppleCD 300i Plus, and I wonder if that means that it would be able to kill two A/UX birds with one stone.
  8. haha No, not the power brick; the base unit! You know, the thing with the logic board in it! It did seem like a fairly widespread thing at the time. I figure it was probably just that desktop computers were still new to the teachers, too, so they weren't all that savvy and probably one teacher called it that and then it spread throughout the school district. It wasn't until my Multimedia Tech class in high school that I learned what all the components inside of a typical desktop computer were. But for some reason I still have this urge to call the old Apple II desktops "CPUs" because of that o
  9. Got the insides cleaned out. Hadn't done the same with the monitor or the PSU before I decided to turn it on and do the PRINT PEEK(64447) command, which returned '0'. The monitor has a great picture, bright and crisp with no burn-in. I did notice when I first turned it on that there were these weird diagonal lines running through it. (Zoom in to see what I mean.) Oh no! Surely everything is terrible and I should just send the whole thing into the landfill. ... OR ... Yeah, just needed to turn the brightness down. Now the picture loo
  10. Thanks for the link! I just tested all the keys on the keyboard, and they feel quite clicky.
  11. So I started cleaning and taking apart the IIc. Some things to notice: Apparently someone had removed the serial sticker, so I have no clue what the serial number is for this machine. Is there any other place beside the box (which is also gone) that lists the serial number? Also interesting to note is that there seemed to be evidence of someone having opened the case before. Note the marks in the plastic in front of the clip: Anyway, opening it up, everything was pretty clean. A quick go with some compressed air and it looks like it
  12. Although, just now thinking, shouldn't the verb be "liberation"? And shouldn't that be the name of the "Conquests" forum? Aaaaaaaanyway, a couple days ago I spotted a Craigslist find that I wasn't able to resist, even though I'd initially had no plans to ever get one: an Apple IIc + monitor for $30! I ended up paying him $40, since he saved me a bit of money by reminding me of the price difference between walking onto the ferry and driving onto it. This guy seemed pretty savvy: he's even donated vintage computers to the Living Computer Museum here in Seattle. The IIc had been given

  14. This project is not dead! My workshop is now almost fully set up, though I do still need to decide what my BGA rework solution is going to be. I've been doing a tonne of research for this project, which resulted in some documents that some might find useful. First is a map of the pins/signals for the 745x chips, as well as the SRAM chips that the schematics specify should be used for the L3 cache. What's that you say? L3 cache in an iMac G4? Oh yes! Turns out the 820-1257 board is wired up for an L3 cache, but Apple just never populated it. It looks like there's just a small handf
