    BGE's take on the Quadra 900/950 ATX PSU Mod

    Really nice! What type of fuse are you using? Fast or slow? And also what is the value?

    New 3D-printed parts (ktkm)

    Congratulations on finding your dream machine! I don’t know exactly what part we’re talking about, but if I had one I think I would be able to make one. Until that day I’m not much of help I’m afraid.

    New 3D-printed parts (ktkm)

    Well, right now I’m working on the aforementioned Quadra 9X0 Nubus slot cover and bezel, a light pipe for II, IIx or IIfx, and a SCSI2SD 5.1 mount for a Mac Portable. Then I would like to find/make a programmer switch for a II, IIx or IIfx.

    New 3D-printed parts (ktkm)

    Interesting thread, and long! Too bad, I missed it. Your thorough take on the Q950 blank bezel makes my efforts appear a little redundant. However, I’m still learning, and I think the right way to start is with the blocky Q950 characteristics. Besides the parts described in the thread, what are...

    New 3D-printed parts (ktkm)

    Thanks :-) Haven’t seen one of those yet, but besides the Nubus slot cover, I’m working on a blank, and eventually a CD-bezel. Right now I’m working with a trial version SketchUp 2019.

    New 3D-printed parts (ktkm)

    A couple of weeks ago, I posted in the Trading Post, about wanting to buy new Nubus slot covers (and CD-Bezel kit), and @elbaroni gave me a clever suggestion to look for 3D-printable parts (https://hackaday.com/2019/01/19/unobtanium-bezels-finally-modeled-for-3d-printing/). But then one of my...

    Apple "mistake? video 512 x 342 vs. 512 x 384

    I always thought 512x342 was an aesthetical choice. Whereas 640x480 is a 4:3 double-page spread -- 512x342 is closer to 2:3 folio (rotated).

    Well, too bad. At least the price felt right. ;-)

    Quadra 950 squeaking noise and distorted video

    Sounds like a useful device now with more batteries to keep track off. I’m starting to understand @Bolle:s straight-edge approach of keeping batteries out, every time I bring home a new old Mac. Regarding PSU, I found this one: ...

    Mac IIci & cache card questions

    I would say the original ’Macintosh IIci Cache’ gives a performance increase with approximately 25%. I haven’t experienced any crashes in particular, and since they are pretty easy to come by, I would certainly go for one if I were you.

    Quadra 950 squeaking noise and distorted video

    Squeaky noise solved (I think). I switched out the extremely large 80ns SIMM:s it came with, to low profile 70ns. Could energy consumption be an issue regarding squeaky memory? Everything seems more reliable now, the energy saver init, that said it didn’t work with the computer model before the...

    Quadra 950 squeaking noise and distorted video

    @Bolle and @BadGoldEagle! I’m so glad you joined! I’m intrigued by the whole ATX thing. @BadGoldEagle I’ve been following your project, it actually made me consider the Quadra 950 in the first place, and now I’m in love with the beast. And after taking the PSU apart, for a good clean, understand...

    Quadra 950 squeaking noise and distorted video

    The distorted video disappeared when I added an extra SCSI hard drive to the chain. Could it perhaps have something to do with the SCSI2SD 5.1 I’m using? The subtle sqeaking noise is still there though. Well, I suppose I’ll have to keep digging …

    Quadra 950 squeaking noise and distorted video

    I’m testing a Quadra 950 in the hope of adding it to my collection. But it makes a subtle squeaking noise (not from the speaker), and the internal video becomes distorted when it reads from the hard drive. If I push down the mouse button, for instance, to make a selection in the main menu in...

    Any interest in a SE/30 internal Nubus adapter?

    Sounds very cool! Would it work with a Thunder IV GX?
