    MacAsm MiniMorse Masochism

    Morse code trivia: the code that everybody uses today is not the one developed by Samuel Morse in 1838. That code was retroactively named American Morse Code, after the rest of the world adopted a different version. American Morse is rather strange, and is now more-or-less extinct. Everybody...

    MacAsm MiniMorse Masochism

    Yes, I have an "extra" class amateur radio license. Initially I was super excited and was constantly using the radio, but I haven't used it so much lately. You're in good company and there are several areas where no talking is involved, or where the only talking is a short exchange in a...

    Mac IIci no video from motherboard, but I do get it from video card.

    Agree with @Byrd, your monitor probably doesn't support composite sync or sync-on-green, which is what the IIci built-in video puts out.

    Macintosh SE/30 logicboard recreation (thread revival)

    If /NUBUS is expected to change slightly after the clock edge, but it's actually changing coincident with the clock edge or even slightly before (not sure if that's possible), then that would make sense. Touching the clock pin would slightly delay the clock and make the problem worse, touching...

    Macintosh SE/30 logicboard recreation (thread revival)

    Do you have any idea what those capacitors are used for? 11pF instead of 33pF is a pretty significant difference and could cause some circuit malfunction. For capacitors in that value range, I'm guessing there are two of them paired with a crystal to create a clock oscillator?

    Macintosh SE/30 logicboard recreation (thread revival)

    A good place to get some expert advice on this might be the EEVblog or the Electrical Engineering Stack Exchange.

    Macintosh SE/30 logicboard recreation (thread revival)

    Good question. You're right the problem might be something else entirely. I only suggested this explanation since it seems to fit the clues, especially the metal probe touching /NUBUS temporarily fixing the problem. And also because if the Reloaded PCB is identical to the original PCB from a...

    Macintosh SE/30 logicboard recreation (thread revival)

    I'd be surprised if a 33pF part were actually 11pF unless the wrong part were used. If you clean the capacitor's pads really well, and also clean the tester pads, and push down on the capacitor body during testing to help ensure a solid electrical contact, does the value change? Of course...

    MacAsm MiniMorse Masochism

    Nice work on the software! If your goal is to learn Morse for amateur radio use, however, most people recommend that you don't try to learn written lists of dashes and dots, or anything visual at all. It's not just less effective, it's actually counterproductive because it teaches mental habits...

    Macintosh SE/30 logicboard recreation (thread revival)

    What happens when a PDS card is installed, does the original problem with video corruption reappear, or is it a different symptom? For tests of adding a capacitor, I don't think it matters much whether the capacitor is connected to +5V or GND.

    Macintosh SE/30 logicboard recreation (thread revival)

    Reading back here a little, it sounds like @croissantking consistently saw the problem disappear when touching a metal probe to /NUBUS. Then they later tried to replicate this effect by adding a 10uF capacitor to /NUBUS, but it caused the video to fail completely. I'd suggest trying again with...

    SE30 Screen artifacts problem

    This is an interesting puzzle! If the problem is happening on multiple Reloaded boards owned by multiple people, including ones with all original components, then it suggests there's something different about the Reloaded board as compared to the original SE/30 board. I believe the Reloaded...

    My New Quadra 800

    Ouch, that PSU looks like it was exhumed from an ancient burial site. And dried leaves? Good luck with the rebuild.

    Getting rid of the 'Your clock is not set to the correct time' alert dialog after System 7 boots

    That sounds like the answer. No need I can think of for anything fancier or to modify the date at shutdown.

    setting up a G4 Tower Quicksilver 933 MHz

    I enjoyed Quinn, thanks for the recommendation @LaPorta. The gameplay feels very fluid and well-polished, but I'd say the difficulty increases too slowly, and it needs more varied sounds. And music. I couldn't get Stronghold to run, it kept complaining that I needed the CD in the drive even...

    Using Basilisk II for PPC under OSX 10.4

    I'm attempting to run Basilisk II build 20091004 on OSX 10.4. The settings are mostly the defaults: Mac IIci, 68030 with FPU, ROM file 368CADFE (the IIci stock ROM), 8MB RAM, 640x480, run in window at 10 Hz. No volumes are mounted, I'm expecting to see a flashing question mark. When I click...

    setting up a G4 Tower Quicksilver 933 MHz

    The problems with the DVI graphics card may simply be a bad card. Today when I booted the Quicksilver, the OSX desktop showed the same pixel noise and glitchy image that I'd seen in OS9 and the boot menu yesterday. Changing to a lower resolution "fixed" it, then I changed back to 1920x1080 again...

    are Classics especially prone to hardware failure?

    Of the first 20 results in today's New Posts list, six of them are about Classic variants with hardware problems or seeking replacement hardware. 6/20 seems like an unusually high fraction for a single Mac category. I've also seen a few people mention that they tend to avoid Classics for...

    Mac on Mac for OSX?

    That's the same ROM I was using originally. I tried it with the 20091004 version of Basilisk II PPC as well as "Nigel's version" 16 and 19, with the default Basilisk preferences. In all cases I only got a solid-colored window when I started the emulator under OSX 10.4.11. It's not terribly...

    Mac on Mac for OSX?

    Thanks for confirming about Mac on Mac. It sounds like a very interesting effort, even if short-lived. As an alternative I've been trying to get some PPC version of Basilisk II running on my Quicksilver, but so far I haven't found any combination of Basilisk II build and ROM version that does...
