    MacViking card found in a SE

    Very cool stuff. 1024x768 (AKA 19" resolution) spread across 24" sounds like about 64DPI? Panasonic PanaPro system was similar, but was 1bit B&W in TPD res on a 19" monitor with SE and NuBus cards. I got the NuBus version for my used IIx. It may have been B&W like the SE before it, but it was...

    Comm Slot II Repoduction?

    Haven't got the link handy, but someone developed a very cool diagnostics card for ComSlot I and his board layout would be the perfect starting point for a ComSlot II project. The mechanics of the interface are done. Rearranging the signals on a riser to match up with a PCI connector as much as...

    does anyone make a atx to MDD converter

    Glad to see that cable is available again, even if it is implemented in straight wiring. The originals were built on a jig so as to match the twists and turns of the OEM part. I've got pics of the jig somewhere, might be useful if only for torquing the straight build into shape?

    MicroMac Power WorkStation - Did anyone ever buy one?

    It probably did, but they likely unbundled it to better recoup development costs? It's a very cool product for expansion alone, even without the multi-slot adapter which I think was probably unbundled as well. That would explain the $199 base price. Then again: "The new upgrade chassis includes...

    MicroMac Power WorkStation - Did anyone ever buy one?

    I was under the impression that the Accelerator was an option, not included in the baseline product. Product pricing seemed to indicate that when I last looked at this stuff. Installation in the WorkStation was outside the scope of the Accelerator's manual? edit: yep pricing info is upthread...

    Disable Radius SE '020 accelerator?

    Has anyone got a Plus with accelerator and FloppyEMU for testing? Curious about that config. Agreed, accelerated machines with SCSI would be far edge cases for stock HD20 support, much less emulated mode. Accelerators broke a lot of software that wasn't written within Apple spec. Bypassing...

    Comm Slot II Repoduction?

    Haven't looked at the CSII NIC in ages, was interested in implementing a NIC of some type in the form factor of the CSII Riser in the TAM at one point. That would have freed CSII cubic for a tightly spaced two Slot PCI riser. Can confirm CSII is a prime example of an Apple customized (bodged...

    128K upgrade developer chimed in . . . what upgrade . . . where's thread?

    Can't remember what the upgrade was, but the guy that developed it was contacted and chimed in with info about it. Does anyone recall that upgrade board, the thread or search terms I might use to find it? :unsure:

    Centris 650

    Thanks for that correction! Now I really need to check out my C650. Never played much with it, was sent to me in trade.

    Centris 650

    Very curious that. ;) When I finally have a chance to get at it, I'll have to check mine. Fabulous case design, not your run-o-the-mill Apple nonsense at all.

    Centris 650

    It's unfortunate that you had the seller check the CPU, no Centris shipped with a full 040. Did it turn out to be the standard LC040 or had it been upgraded with a full 040 at some point? Good luck making some use of it

    NuBusFPGA: HDMI on NuBus Macs

    'nuf said, didn't realize linearity of the process comes into play. You'd need to hold a mimimum of three to five lines in memory to have enough information to give the groups of four pixels a "better" distribution values than you get by doubling s single pixel data point across the four pixels...

    NuBusFPGA: HDMI on NuBus Macs

    I've always wondered if the Q630/PPC Performa Video Slot native pixel doubled 320x240-640x480 setup involved any interpolation in the doubling process. Picture appears to be much too clear in 640x480 than 320x240 would be if mapped directly to four identical pixels by the process you've...

    Twentieth Anniversary Macintosh G4 (!)

    WOW! 😲 Neat trick, but slower?

    The Performa 6200 wasn’t really a road Apple - here’s why:

    I think you're spot-on, Q630/LC6xx and PowerBook 190 were transitional, low end market tier offerings and almost without doubt, solid plans for upgrading the logic boards in their brand new case designs. They utilized the best of the old married to the newer technologies to come. The shift to...

    The Performa 6200 wasn’t really a road Apple - here’s why:

    So in your testing, SCSI/IDE is a wash performance wise in the 6200 with IDE running away in price/MB and dirt cheap CF/SD compatibility quite handily?

    Macuserman's Junk Collection

    Cheap hobby, far less expensive than an addiction to that incredibly silly, non-sport game involving expensive sticks and ludicrous, overpriced attire. Anybody here do ski weekends? I rest my case. :p edit: we learn a lot of useless crap along with useful knowledge, valuable experience and...
