    SE/30 Simasima Repair: 6 faults fixed and a working Mac

    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...

    Looking for reliable repairs - Recap & pad repair for a Macintosh Performa 460 (LC3+)

    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...

    New tool to remove capacitor and rust corrosion - the dental scaler!

    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.

    A Tale of Two Classics

    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...

    PowerBook 100 RAM Expansion Pinout - New RAM Card Build Issue

    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...

    Micromac Performer Clone - Issues with Mac Plus

    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...

    Micromac Performer Clone - Issues with Mac Plus

    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...

    Micromac Performer Clone - Issues with Mac Plus

    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...

    Issues with Novy Quik30 & Mac Plus

    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...

    Heat gun recs?

    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.

    Micromac Performer Clone - Issues with Mac Plus

    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...
