Fun looking support structure! Did you have some trouble with layer shifting during the print?

Great job with a very stubborn board! Goes to show that capacitor leakage can often be just as frustrating as an exploded battery, and nothing is a guaranteed "just needs a recap." Is it safe to say that the coming out of reset delay was caused by the sound chip? I'd be interested in whether it...

Sure thing, send me a message and we can discuss.

It's been a couple months now, but if I recall, the LCIII required me to drill through the via connected to the missing pad, and run a wire through to solder to the birdseed component on the bottom. The remaining repairs I was able to slide the cap over just enough to solder to the ground plane...

Thanks Mike - happy to help!

Wow - great idea on the dental tool! I've tried using an old Sonicare toothbrush for things like this, but it was never abrasive enough. I didn't realize Amazon had these scaling tools for relatively cheap.

One of my first Mac purchases after getting back into the hobby was a Classic from a nice lady in Minneapolis. I don't think I paid much for it, but had I taken the time to shake it first... well, I should have paid less! I was able to eventually restore the entire thing to working shape, but I...

For the past few months, I've been working on a design for the PowerBook 100 - a 6MB RAM expansion containing 12 512k x 8 PSRAM chips. I have a few PB100s, but only one had an upgrade past the stock 2MB expansion card. Based on what I read in the Developer's Note, if I choose to do so, I can...

Hi All - one more update. I tried the GemStart drivers and ran into similar issues - very unstable and crashed almost instantly. There are no jumper settings on the Performer board, but it should pull +5VDC from the PDS. Good call on the voltage check. I reflowed all the solder joints but...

Hello and thank you for the reply! I gave this a shot yesterday... no dice. The extension does load properly in System 6, and it will boot, but the second I try and do anything, the system gets unhappy. Trying to open the "About this Macintosh" window resulted in an illegal instruction bomb...

Still waiting for the Retro Platinum to come back in stock… been patiently hoping for months!

I'm throwing in the towel on functionality beyond the SE. I built an entirely new board, tested it on the SE, and it still didn't work on the Plus. I bought another 68000 socket, installed it on a different known-good Plus board, and still nothing. It boots into System 6 but will crash upon...

Hi Chris, Sounds like a neat system you've got there! My first suggestion would have been to clean the Killy clip - but you've already done that and reseated the accelerator. You mention it's a Plus - have you checked the analog board and logic board for cracked solder joints at the connector...

If you're just starting out, and have never used a heat gun - I wouldn't (at least not yet). There's no need for one when recapping an SE/30. If you need to start pulling PLCCs off, then you could make the case for one. The SE/30 is old enough now that the old caps almost fall right off without...

Apple part numbers 661-0920, 614-0039. Mine was dusty, but didn't show any signs of significant capacitor leakage.

I've been trying off and on for the past year to adapt one of these wonderful Bolle clones to my Macintosh Plus. I am running out of things to try, so I figured now is the time to throw out a request for help! I've got GAL16V8Ds installed (including the optional one at position U7), the 68030...

That's some serious damage cleaned up... well done! I've found the 610 boards to be temperamental, so nice work getting a few working. As for the audio issue, I've run into failed DFACs in the past. Given you have a few "dead" boards, I would try swapping U15 with one from a donor board. I don't...

I regularly use an HP MJF printer at work with PA-12. That material is extremely tough, but does flex more if the walls are thin when compared to FDM prints of the same thickness (1-2mm or so). That said, good luck actually snapping the MJF part in two - they're extremely durable. I have exposed...

Like I mentioned, this drive isn't currently working. Neither LED on the small PCB illuminate, and it won't read any discs. I was really hoping it would be as simple as swapping some capacitors, but there aren't any leaking from what I can see. Cleaning the laser lens didn't do anything either...

I have a few of these drives, and wanted to see how different they were from the more commonly found "caddy" drives inside the AppleCD SC Plus, CD150, and so on. This example I show below is not currently working. My thought was to repair it in the same way I've done in the past - replace the...
