On the off chance this interests anyone, I've verified that the analyzer and test host are compatible with the PIC12F1822 as well as the PIC12F1840, and made the small modifications necessary for them to to so. (The test device requires the 1840's larger SRAM, so it is not compatible with the...

Your Raspberry Pi will need a TashTalk hat or something similar. You can then run TashRouter (to route from LocalTalk to EtherTalk) and Netatalk (to share files/printers) on the Pi. Same deal as 1 except you don't need a TashTalk hat and TashRouter will be bridging from LToUDP (instead of...

Ooh, this is Relevant To My Interests. I tried something similar a while back, creating a collection of programs that together amounted to a userspace inetd for AppleTalk, but got stuck somewhere in PAP-land... I'm interested in having a peek at the source whenever you release it.

Need a TashTalk hat? Maybe something else?

Check that the phone cables you're using have four pins - PhoneNet uses the second pair, and the average phone cable doesn't bother with anything but the innermost pair.

Updated the pinout diagram at the top of the .asm file and added a pinout document to the documentation directory to hopefully clear up any ambiguities in future. No binary change so not doing a release.

0 = both feet on accelerator 1 = both feet on brake A 128-byte buffer that must never, never, never overflow or underflow while conveying frames that can be up to 605 bytes (well, 1023, actually) in length, with "here be dragons" as the stated consequence... really, sometimes I'm amazed it...

This is true. Still, maybe I ought to rebrand it to "flow control output" or something more generic, if for no other reason than "RTS" and "CTS" are also used by LocalTalk to refer to control frames, further muddying the waters...

Your read is correct: the CTS pin is a flow control output used to signal the other end of the connection whether or not it should hold off sending data to TashTalk, and if it isn't respected, TashTalk is virtually guaranteed to get into a bad state. I'm realizing that I likely helped to...

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...

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...

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...

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.
