    ITXPlus: A ITX Sized Macintosh Plus Logicboard Reproduction

    I think that's what this board does, unless by "the floppy plug", you mean a 19-pin D-sub. That's what I would have reached for at first, but as far as I know they're unobtanium...

    TashSync: Macintosh Video Sync Signal Converter/Generator

    It doesn't manifest everywhere, but the fact that it manifests anywhere is a source of consternation. In hindsight, I really should've guessed this would be a problem, but I was a little bit obsessed with using a PIC that was available in a SOT-23 package, heh...

    TashSync: Macintosh Video Sync Signal Converter/Generator

    Guess I never updated this thread. Early testing results showed some jitter which revealed a fatal flaw in my assumptions - specifically, that the PIC10F320 would be able to generate the vertical sync signal in software (since it only has one configurable logic cell, used for the horizontal...

    ITXPlus: A ITX Sized Macintosh Plus Logicboard Reproduction

    For anyone interested, I've made a daughterboard for the ITXPlus that allows the addition of an IWM or SWIM chip in DIP-28 form. It mates with the 2x12 header on the ITXPlus and provides a pair of floppy headers, ready for your Floppy Emu, TashTwenty, or even actual floppy drive! Also made an...

    Anyone have a copy of "AppleTalk Phase 2 Protocol Specification" (C0144LL/A)?

    Yes, thanks for this! It's been sufficiently long since I worked on TashRouter that a lot of the knowledge required for it has bit-rotted in my brain. Any help that anyone can provide as to what changes this is going to require would be most appreciated...

    Cloning the IWM (sort of)

    To the best of my knowledge, the IWM used by the Mac is functionally identical to the ones used by later Apple IIs.

    Cloning the IWM (sort of)

    Have you seen this already? As far as I'm aware, this is the most complete documentation for the original IWM. There's also Understanding the Apple II's chapter on the Disk II, which fleshes out the technical details of the hardware on which the IWM is based. (If you find these useful, maybe...

    TashPad: Super Nintendo to Gravis GamePad ADB Converter

    Nice build! Sorry about the incompatible controller. I wonder what the issue might be, the protocol is pretty simple as I recall. If you want to send me one of the problematic controllers, I can take a look, though I don't know how soon I'll be able to get to it. Alternatively, if you've got...

    Performer Pro in a Mac Classic

    What does the accelerator do with the ROM of the Classic? If it patches the Sony driver, it's possible that it gets rid of the HD20 support.

    Tashtari's Miscellaneous Macintosh PCBs

    The parts I use for the TashSync boards are easily repurposed into a passive Mac video to VGA converter. I'm sure I'm not the first to do one of these, but this might be the most compact one out there - it's barely bigger than the two connectors! Despite this, it uses all through-hole parts...

    TashSync: Macintosh Video Sync Signal Converter/Generator

    I'm really quite pleased with myself for the design of these boards, everything fits together so neatly. The bulk cap even snaps right in between the DIP socket and the DA-15 so the leads don't need to be bent to retain it while soldering it. Once I'm satisfied with the firmware, I might even...

    TashSync: Macintosh Video Sync Signal Converter/Generator

    OKAY! Finally finally, the final (at least I hope) PCBs are here. I'd like to send a few of these out for testing... The perfect candidate would have: A II-series machine with a Toby card, a IIsi/IIci, or both A decent-sized collection of VGA monitors that are known not to work with the...

    Anyone have a Powerbook 100 and a Floppy Emu?

    Thanks! I have updated my compatibility matrices accordingly.

    Anyone have a Powerbook 100 and a Floppy Emu?

    Nice work! I'd be interested to know the answer to this, too. I thought that the IIx, like the IIcx, required the ROMinator or some other nonstandard ROM for DCD support... and that the IIfx didn't support DCDs at all, probably due to the SWIM being handled by a coprocessor. In any case, I...
