Special Apple owned PowerMac G5 7,2 found!
JRL replied to Recaptcha's topic in G3/G4/G5 Power Mac, iMac & eMac
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

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.

Sonnet Crescendo L2 G3 upgrade model compatibility
JRL replied to jessenator's topic in PCI Power Mac & Performa
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. -

Weird set of SE/30 issues - fast chimes/no sound otherwise
JRL replied to JRL's topic in Compact Mac
Ah I see. Yeah I can confirm that these caps are all the exact same voltage as the originals. -

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. -

JRL replied to JRL's topic in Compact Mac
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 -
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,

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.

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.
