    Help with XT Turbo Clone

    The Faraday FE2010A is actually the chipset. Your CPU is actually that Sony-branded chip to the left of the Faraday chip in the photo. Good news: it’s actually a second-sourced NEC V20! Thought you would like to know so that when you get this fixed, if you wanted to use the XT-IDE Universal...

    Need Help with Sony CR-44 Power Supply

    I have two Macintosh SE computers, both have Sony CR-44 power supplies. I have recapped one of these supplies with a kit from Console5. Both power supplies are exhibiting the same issue: the 12V output is measuring nearly 12.8V, which is definitely out of spec and is causing artifacts on the...

    Best Way to Show Image Full Screen (without menu bar)

    Forget fancy Photoshop trickery to pull it off, I would like to show a 512x384 image full-screen on my Macintosh SE for video thumbnail creation. What is the best way to pull this off? Rounded corners are OK, but I don't want the pesky menu bar or mouse cursor getting in the way. I'm open to...

    Need Help Identify an E-Machines NuBus Video Card...

    I usually like knowing what I am buying before using "Buy It Now" on eBay... but when you see an E-Machines video card pop-up on eBay what will cost you $29 shipped (OK, $29.01), and there's a good chance that card is QuickDraw accelerated, then you just buy it now and figure out what it is...

    If you're ever in my office perusing my bookshelf of computer references, there is one odd title you will run across: It is "Scooter Computer & Mr. Chips: The Computer in the Candy Store" by Leslie McGuire. And while it is not my childhood copy of the book, it's there for a reason: one of my...

    Kansas Fest happens in July, and what better lead-up to that event is there than a Month to celebrate the Apple ][, including it's clones and related cousins (the Apple I and the Apple ///) on social media? I can't think of a better way, either! So let's figuratively blow-up social media and...

    The C-Ltd. SCSI-1000 for My Amiga 1000, and I Need Help Getting it Working (Disk Woes)

    I just want to be able to use a mass storage device with my Amiga 1000... so when I saw this C-Ltd. SCSI-1000 appear on eBay, I bought it now. Maybe I should have done some research first. Maybe I should have spent twice as much and just bought a Parceiro (assuming you can get them still). But...

    Which Macintoshes, NuBus Video Cards Only Do “Sync on Green”?

    And according to 68kMLA at https://68kmla.org/bb/index.php?threads/getting-1152x870-on-a-650-with-a-non-apple-multiple-sync-monitor.40039/: Great, the OP here only specified “early Apple NuBus video cards” here without naming them. But I suspected that some existed. Which is why I wanted to...

    Which Macintoshes, NuBus Video Cards Only Do “Sync on Green”?

    The Higher Intellect Vintage Wiki states that the IIci shares video chips with the IIsi, and this may need a sync on green monitor: https://wiki.preterhuman.net/Macintosh_IIci Chris Xodium’s Retro Haus on YouTube didn’t want to go out to his garage to get his sync on green monitor to test his...

    Which Macintoshes, NuBus Video Cards Only Do “Sync on Green”?

    Turns out I have several and didn’t realize it because I thought they were too new. I had grabbed some Dell LCD monitors they were scraping at work and their data sheets say they do sync on green. If my IIci power supply wasn’t currently disassembled for re-capping, I would put it to the test...

    Which Dell monitor is that (assuming you're not using some sort of adapter to separate the sync from the green)?

    Which Macintoshes, NuBus Video Cards Only Do “Sync on Green”?

    Based on information that I found online, the on-board video on the Macintosh IIci and Macintosh IIsi only support “sync on green” mode, which is a problem if you don’t have a monitor/scaler or other video device which supports this mode. Well, I have a IIci, but nothing old enough to do sync...

    Generic IC Cross-Reference for "Proprietary" 8-Pin ICs Used in Macintosh Power Supplies

    In my IIci power supply, the mystery chip is simply labeled “0600” with a date code of “9011J”. There’s no manufacturers name or mark on the chip.

    Generic IC Cross-Reference for "Proprietary" 8-Pin ICs Used in Macintosh Power Supplies

    I have a Macintosh IIci with an Astec Power Supply. During my last livestream, someone asked me if the power supply had the "infamous" daughter board... to which I had to answer yes. I think they mentioned it was due to the op amp on the board... or was it an optoisolator? I was trying to solder...
