Finally got around to making available the board files and Gerbers for the kits that I've sold (and continue to sell) in my Ko-fi shop, in case you want to manufacture your own instead of buying kits from me. Also put my HDI-20 adapter board there, and will probably put future small project...

It's time for another Tashtari shenanigan. (You don't see that word used in the singular very often, do you...) So here's the situation: I'm about 99.9% sure that the Powerbook 100 has HD20/DCD support in ROM, but I want to be 100% sure. As with all machines with HD20/DCD support, the device...

I have a "syncing" feeling it's time for another TashProject... Introducing... TashSync! Elevator Pitch It's a video sync signal conversion/generation firmware for Macs, targeting the PIC12F1501 (8 pins, 77¢ in quantity) microcontroller. Primarily, it takes a "composite" video sync signal...

Ladies and gentlemen, my next trick is impossible improbable... It seems like the IWM is the only (or at least the biggest) thing standing in the way of a Plus or SE made of entirely new parts - and possibly also the biggest problem for those trying to revive an old board. For completeness's...

Starting a new thread so as not to derail the Netatalk 4.0 thread... How big a lift would it be to implement support for user-space AppleTalk in Netatalk? I'm thinking, I suppose, of a modular system along the lines of what TashRouter does, with modules for EtherTalk over tap, EtherTalk over...

Does anyone remember having seen a piece of Mac software that had a semi-Windows style "working in background" cursor? That is, an arrow but with a small watch (or perhaps beachball) off to the right side of it. I could swear I've seen this somewhere but I can't remember where. I'm trying...

This is probably a long shot considering how rare MacCharlies are, but... I find myself curious about the keyboard unit that came with them. If it plugged into the Mac's keyboard port (the one with the 4P4C phone headset-type jack), it's one of a very small number of devices that did, and maybe...

In writing TashRouter, I denigrated AsantéTalk and LocalTalk/EtherTalk bridges in general as being hackish solutions replete with protocol violations... which they are, but they remain popular and regularly fetch $100+ on ebay. I'm realizing that's at least partially because they're pretty much...

I don't know if quadrature mice are as hard/expensive to come by as Plus/512k/128k keyboards are, but in case you need one on the cheap, I've made some PIC firmware for a PS/2 mouse converter. Like the Plus/512k/128k keyboard converter I made, I'm sure this has been done before somewhere, but I...

I'm sure someone's done this before, but I enjoyed the challenge (I used all but 61 words of program memory and all but 4 bytes of SRAM!)... I made some firmware for the PIC12F1501 that lets a PS/2 keyboard be used with a Mac Plus or the other Macs that used the phone-cord keyboard. It makes...

Elevate your game! Introducing... TashPad! Elevator Pitch It's a converter that makes a Super Nintendo/Super Famicom controller appear to an ADB Macintosh as a Gravis Mac GamePad. Used with the GamePad's control panel, it can be used to play all your favorite Mac games. I made the...

I find myself in need of someone to perform a couple of small experiments for me... Experiment 1: Open Key Caps or something else with a text box that supports arrow keys Hold down the shift key Hold down the keypad +/left-arrow key until it starts repeatedly inserting + signs While still...

MacRecorders are still fetching $100+ on ebay, it seems like a market ripe for puncturing... There seems to be a schematic out there from BMUG that claims to be similar, but looking at it, it doesn't quite match what I understand about the MacRecorder. Mainly, the sample rate doesn't match...

This topic's been touched on in a handful of threads previously, but as far as I know, the question's never been settled. What kind of transformer (that you can buy new) would work for making a homemade LocalTalk/PhoneNet dongle? Inside AppleTalk (2nd ed, page A-6) gives the following...

Of all my PIC projects, this one is probably not the most practical, but I think it's cool and it was fun to make, so here it is. =) Introducing... PicoATP! Elevator Pitch It's a tiny AppleTalk stack for 8-bit PICs, coming in at under 1024 words of PIC assembly, and while the code targets...

This page mentions the existence of something called the HyperCard AppleTalk Toolkit, apparently a set of XCMDs/XFCNs that allow the user to use AppleTalk ATP and NBP from HyperCard stacks. I'd love to get my hands on such a thing, but mentions of it anywhere else are scanty... does anyone know...

So without going into too much detail, I have a slightly mad idea involving bitbanging the Mac floppy interface from a PIC, and I kind of want to know how mad it is. By way of background, the Mac uses the "phase" lines on the IWM/SWIM chip (originally intended for controlling the drive head's...

I've been working on this for a bit, ever since reaching an inflection point with TashRouter, and I'd like to throw a rough design out there for comments... So, the basic idea here is to realize the dream of a userspace AppleTalk stack in an incremental and modular way (that way I don't...

I'm sure there are plenty out there who are better at finding this stuff than I am, so I'm seeking help... What I'm looking for is protocol-level information on the protocol used by Apple Events, I'm not entirely sure what it's called, but I know that the service type it announces to NBP is...

If so, I wonder if you might be willing to do me a small favor... I'm seeking a trace of the AppleTalk network activity between Mac and ImageWriter when a print job is being sent. There are a few different ways to collect such a trace: If you have an AirTalk and Mini vMac v37 with LToUDP, you...
