  1. Most likely was used as an office computer at Apple at some point that could have entered the general resale market through a number of means. One of the Apple employees I purchased some prototypes from had told me (in his building at least) that when the office was done with Macs that were used in the office that they would just leave them out in the "trash" for employees to take if they wanted them. He picked up an IIci with similar expensed equipment tags in ~1994 this way. In any case a very cool find!

    Thanks Jon! I think it's a plain LC040 but I can't see the screen well enough, unfortunately. It does seem to be the exact same panel as the stock 520 but I haven't cracked it open to be sure just yet. I'll probably want to keep it the way it is since it is a prototype, thanks though C! That's what I figured - I haven't seen a cap reference but I'll probably try and find one soon. I have a spare working 520 screen in any case.

    So I visited a local ewaste plant recommended to me by @olePigeon - thank you again! Unfortunately a lot of their vintage Apple stuff had Maxell bombs or was water damaged, but there's a lot of salvageable stuff. For $350 I picked up: 3 IIcis SE FDHD Amdek composite monitor Duo Disk 2 early Disk II drives with rainbow cord Duo Dock with a really rough looking Duo 230 stuck inside PB 520 with PCMCIA revA card cage 17" vintage Sony Trinitron CRT Examining the 520 - I thought it was normal (nothing crazy with it on the outside), but

    Some more photos of the Newtons I got earlier, still messing with them!

    Been going pretty crazy with YAJ/Buyee purchases lately, whoops. Some of the cooler things I've gotten (paid a lot for the DiiMO upgrade but I had wanted one for years) The Interware upgrade is sealed inside. Also bought a nice looking Nextstation Mono from @archer174 (along with an SE in an SE case and 12" RGB), it was great meeting you! Also visited the Apple engineer who I got the Newton stuff/PB 100, bought a nice looking PB G3 Lombard and another LC. The LC is standard but it had a Dynacomp power supply with an orange "Not approved by the FCC label
  6. Following - I have a Q700 with this exact same issue

    Nice score! I did see that ad but unfortunately I couldn't show up to Mountain View in the morning.
  8. Sorry to interrupt the Sonnet-centric discussion but in case this info helps - I picked up an Interware Booster (320mhz l2, same as the Vimage mentioned in LEM) and it doesn’t state compatibility with the Tanzania based clones. I could try it in my 4400 though.
  9. Ah I see. Yeah I can confirm that these caps are all the exact same voltage as the originals.
  10. AVX tantalums and Nichicon axials (the same ones I’ve done all of my personal boards with). I ESR tested every cap and all joints were redone to be sure.
  11. Yeah, they're also pitched up. Occasionally the chimes also glitch out completely (random tones) I forgot to mention, when booting from my test HD the board would sometimes bomb due to lack of available memory to load any given extension or system file (seemingly random) I'll have to check the lines later, thanks @Bolle
  12. So I'm repairing another forum member's SE/30 motherboard. Previously it didn't chime at all and would stay stuck on a grey screen. After the recap, it works - somewhat. It always chimes (boot/death chime) at a very fast rate - probably like 2x-3x the normal speed. Sometimes, it death chimes at a grey screen, other times I've gotten it to boot off an HD (it sometimes hangs on the Welcome to Macintosh screen - the HD is known good). No other sounds work. I've read up on other death chime issues with the SE/30 but I'm not sure what the fast chimes could mean,
  13. Yeah, my recapped original PB 100 PSU would never work right with any of my PB 100s that had the fuse fix applied from the factory. Even on the ones I have without the fix it would work, but there would be odd issues such as the screen flickering when I pressed a keyboard key. I think it's likely a semiconductor in the psu that's the problem.
  14. Hey Jordi, Yeah, with my 150s “Low Power AC Adapter” it works great now. I would give it a try if you have one spare.
  15. Whoops, I was indeed not being smart with how I set up GemStart. Works great now!
  16. Hi all, As I mentioned in my Conquests thread, I picked up some Apple schematics that might be of interest. Sorry, they are scans of copies so the quality isn't the greatest. I will try and rescan them with my work scanner.

    Messed with the Newtons further, the two DVT units in the first picture of them have an unreleased Newton OS (1.4). Took some more pictures of some of the units here: https://imgur.com/a/pOexZO2 https://imgur.com/a/D7izgqu Also took a look at the schematics I got - some ADB related schematics (including the schematics for the Apple Keyboard and Keyboard II) and schematics for the 256/512k VRAM SIMMS, among others. I'll upload them hopefully soon.

    Big news... Picked up a PowerBook 100 system from CL a week or so ago, recapped everything and fixed the HD as usual and it works great. It turns out that the guy who sold me the PB worked for component engineering for Apple for a while on quite a few projects, including the Newton 1xx series. He sold me the rest of his Newton stuff, including his prototypes. https://imgur.com/a/uCop4OI There were 9 Newtons in total that all were apparently used in the dev process but these are the most notable ones. The clear Newton has a normal front as he swa
  19. So I picked up a dual SE FDHD with a Total Systems Mercury upgrade (16 MHz 030), and it's having a weird set of problems. The original motherboard came to me with a shot SCSI bus so for now I decided to move the FDHD roms and upgrade to another SE board I had here. Right now, there are the following issues: -The 16 MHz '030 is recognized as a 16 MHz '020 by Tattletech/Techtool/etc.. -Both versions of Gemstart don't want anything to do with the board (they act as if no card was installed at all) -The card has a 68882 FPU installed (not original to the ca
  20. I have an extra SE logic that I tested recently - where are you located? Feel free to message me
  21. For those wondering, I found the issue - it was the adapter. The PB 100 boots great from my PB 150's "low power" adapter. Guess one of the ICs in my recapped adapter went bad - this PB has an additional fuse fix from the factory so it could be drawing more power.
  22. Nice work! Do you mind pointing where DZ6 is? (Sorry, I can’t seem to see it in the pic) I have a 210 with the exact same gray screen issue right now...
  23. I sold that 575 to another MLA member actually! This is another one that I never had the motherboard with. I kept my own LC 575
  24. Yay, it's looking great!! Happy that it went to a great home
