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...

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...

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

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...

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...

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.

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...

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...

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...

If memory serves, PNTG is MacPaint...

Thanks! I have updated my compatibility matrices accordingly.

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...

Forgot to update this thread - I have five of the new PCBs that should fit directly into the Floppy Emu and the connectors to go with them - anyone who wants them, please get in touch!

That was what I originally wanted to call it, too, but apparently there's some smaller connector that that refers to... can't find the details now, but I successfully confused someone with it once.

oh, and, since I'm in a pedantic mood: NO NO NO NO NO What we will do is set the record straight. The second letter in the name of a D-sub connector denotes the shell size, and the B in DB-25 refers specifically to the shell size that contains 25 (sometimes 44 or 52) pins. The Macintosh...

Thanks. =D Smol detail to correct with the PCBs, the board is slightly too wide and the DA-15 doesn't sit quite flush with its edge - so it's going to get even smaller in the next and hopefully final revision, after which I'll offer a handful of kits for sale. I'm also spinning a passive DA-15...

PCBs are here at last! And parts... mostly. Digikey made a boob and sent me LM358s instead of PIC10F320s. But here, substituting a PIC10F322, it is! That's a 22 µF aluminum polymer cap (used at the suggestion of @cheesestraws in lieu of a tantalum), an 0.1 µF ceramic cap, and a 330 Ω...

Before we change the subject - who wants the new adapter PCB and hasn't soldered their connectors yet? I'm wondering if I should throw some more connectors into my next Digikey order...

It certainly would be the most straightforward solution from a user's perspective, and it could be incorporated easily into "Mac in an FPGA" type projects. I just don't know if I can actually do it. =) I haven't given up yet, though. True, though the Atmel fitters are also very old and very...

Well, if I can get the RPi working with PREEMPT_RT as the frontend, you should be able to mount any filesystem that Linux can read. I made up an RPi hat for that purpose and have sent it to JLCPCB to be fabbed, so now it's just ("just") a matter of the software side of things... that'd be my...
