    Beige G3 Locks Up at Welcome to Macintosh Screen?

    I'm relatively sure OS 9 runs a second memory test including a cache test at the point shown. Failing the cache test usually produces a message to contact a service technician, so I'd start by pulling some of the RAM to see if it's stable in a reduced configuration. If you were able to get...

    I'm still after one of those RasterOps cards too, they're far less common than the Thunder/24. If you track down a DSP card for the SuperMac, the ones marked 'Image Processing Accelerator' run their two DSP16As at 64MHz and the 'GX' branded ones are run at 80MHz.

    Both can accept DSP daughterboards (pretty sure the RasterOps would be identified as a Horizon 24 if populated.) The GWorld RAM is unique to these and the 8•24 GC, and compatible sticks are hard to find for these! If you have a moment to take closeups of the RAM chips I'd be thankful :)

    I've heard rumors of the RasterOps being legendary though I haven't been able to find any performance data or even resolution capabilities beyond the RasterOps matrix on Gamba's site, which indicates it's at least good for 1152x870@24-bit.

    Looks like a RasterOps PaintBoard Pro and a SuperMac Thunder/24, both very strong options. As DSP capable cards go, the SuperMac isn't as fast as the later Thunder II or Radius Thunder IV but is still very quick.

    Best Quicksilver Graphics Card?

    The Radeon 9000 Pro is going to be the most commonly available G4-ADC 9/X accelerated card. There's also the Geforce4 Ti4600 which has G4-ADC, very quick acceleration in 9, but only emulates Quartz Extreme in OSX (so isn't a great choice there despite strong numbers.) It's also noted to have a...

    How many floppy drives can a SWIM chip control? (just curious)

    Looks like the SE uses an additional GLU chip to control both internal drives on /ENBL1 (assume the portable does the same,) still only two /ENBL lines on the IWM itself. ⌘⇧1 - Eject Drive 1 ⌘⇧2 - Eject Drive 2 ⌘⇧0 - Eject Drive 3 ~need to test this but if memory serves...

    How many floppy drives can a SWIM chip control? (just curious)

    Thanks for this tidbit, I had assumed it was a high quality homebrew job but it makes more sense to be one of the AE units. There's no identifying information on it though, so I may never have found out. It seems they cut into a II/IIx/IIfx blank to fit the connector... A mod to make it fit...

    How many floppy drives can a SWIM chip control? (just curious)

    My recollection is rusty, but I had thought the Macintosh implementation of IWM/SWIM only allows for one drive per port, which is why the daisy chain port on external drives is often plugged with a plastic cover. Apple IIs IWM could use the daisy chain feature for up to two 5.25 and two 3.5"...

    Who has a iMac G3 with either a Sonnet Harmoni processor upgrade and or a item that uses the Mezzanine slot?

    I haven't grabbed a Rev A/B, but I have stored pictures away as the auctions have gone by. Here's what I've seen: --- First, there's the Griffin iPort, which uses the physical slot opening but not actually the mezzanine interface. The PCB runs cables to the standard 8-pin mini-din serial...

    The Great Gazelle PCI Hack Thread, Part 2

    Well I'm confused... could've sworn I hit 'post' over on the eBay finds thread tab I had open, but when I went checking that thread today I found the post was here instead. Sorry about that!

    The Great Gazelle PCI Hack Thread, Part 2

    Haven't seen one of these before... "486 Module" from Reply Corp in 1991 - could be another prototype to the DOS cards that Apple/Reply first built. $200 BIN or offer. If I knew more about how it works I might bite... ;) https://www.ebay.com/itm/184945310628

    Benchmarking Mac II NuBus Networking (A/ROSE, OpenTransport)

    The biggest advantage I've found when using the A/ROSE card is that its host system will respond nearly as quickly under load as it will when idle. Practically, this only matters when I'm connected to the A/ROSE "server" computer from a different "remote" Mac and transferring files using the...

    TAM speaker grille

    I don't have specific advice for cleaning, but the grilles are very easy to remove- they're just held in with a little friction along six round stubs. Pull carefully but firmly and they'll pop right off. I added a picture in case it helps. Is the fabric discolored, or just not opaque enough to...

    x86 card revival thread

    Thanks @wthww for mentioning revised posting limits in the bug tracker. Let's try this again... -- These have been a fascination ever since I eight-year-old me tried aimlessly to make my Performa run exe files. I've acquired several x86 cards over many years and although there are many...

    Thanks for keeping this one alive. I can re-post any of those OF .properties dumps I posted before if it would be helpful.

    x86 card revival thread

    Well I tried to recreate this faithfully but the posting system here won't allow posts over 10k characters, nor will it allow me to upload a docx file. For lack of a better idea, here's a zip of an HTML version of the word doc :/ At least everything from the top post of the old thread is in...

    VRAM SIMMs for Macintosh Display Card 4•8

    I went and found my post but I never actually linked the pictures, only an ebay auction which has long since ended.  Here are the ones I have working in mine:

    TiBook 1GHz w/ OS 9.2.2 — anyone got RTL8169x PC Card working?

    I haven't tried using an 8169 PC card, though I have tried a PCI card version in a 9600 using the driver attached (likely identical to the one you have.) It seemed to hang up the first time I tried it, but after some general troubleshooting (reselecting the default extension set, cold boot, PRAM...
