Apple Desktop Bus Protocol (2021)

ADB was pretty solid. A shared-single-wire bus that allows multiple slaves by including an address in the message... but includes a protocol-level reset that's used regularly, so a missed single bit doesn't jam things up unrecoverably. When I think of how many fewer hours of my life I would have wasted had I2C learned this lesson...
buildbot•2mo ago
Oh is that why I2C seems to just hang/break whenever I use it for a DIY project? Does everyone just reset the bus all the time?
addaon•2mo ago
The I2C protocol is a distributed state machine. Each slave node needs to know what bit in the message sequence is being sent, to match it against its own address. As a result, a single missed bit results in a slave not recognizing its own address and going dark -- or, worse but rarer, potentially recognizing its address in the midst of data sent to another slave, and responding inappropriately. Observing this in a real system indicates either a signal integrity issue or a bug, but signal integrity issues do happen, and this non-recoverable behavior is somewhat unique to I2C, and somewhat cursed, turning what would be a transient error into a permanent one. In practice, most I2C devices have some mechanism for recovering (sufficiently long pulse on clock line, so many clock edges all low, a dedicated reset pin); and for the few that don't, forcing a reset of the device through a high-side drive or similar works fine; but the fact that these mechanisms are outside of the protocol, rather than inside it, is also cursed, and means that for an I2C bus of mixed devices there's not guaranteed to be a single method acceptable to all of them.
eternityforest•2mo ago
Yes, but every device is slightly different and sometimes you need obnoxious hacks to even detect that there is a problem at all...
JKCalhoun•2mo ago
The only thing was… it was very easy to destroy a device (keyboard for example) if you hot-plugged it. I lost a keyboard or two (well, my employer did) because I plugged in a device without first powering down the Mac. (Unlikely the ADB protocol though? I wonder if this is one of those examples where having some pins longer than others so they get electrical contact first could have prevented the problem.)

As the author mentions doing it, a note regarding retrobright: it seems to cause faster yellowing than not using it. https://youtu.be/_n_WpjseCXA

Maybe just let your items show their age.

inferiorhuman•2mo ago
Honestly it'd be really cool to see some repro parts for these like an upper case (even without the Apple logo).

I junked my old AE2 ages ago and finally got a replacement today. If I knew then what I know now I would've salvaged a bunch of stuff off of it. Oh well.

djmips•2mo ago
That's a data point but that video is an opinion stated as a fact. You'll find others who have different results. It would be nice if there was some actual research.
zdw•2mo ago
Has anyone calculated or measured the input lag of ADB vs other protocols such as PS/2 or USB? This is unfortunately hard to search because most references on the web to ADB are for the Android Debug Bridge.

From the numbers given, it seems like ~2ms to send a packet (my math may be off), which is quite good when compared with other contemporary/modern protocols (see: https://danluu.com/input-lag/ for examples)

justin66•2mo ago
It's okay. It's not as good as the SIO that came with the Atari 8-bit computers, but it's alright.
leoc•2mo ago
Steve Wozniak was supposedly invoved in the design of ADB, but it's so hard to confirm that that I'm starting to wonder if it's a myth. The closest to confirmation I can find is a reference to "the ADB, created by Steve Wozniak" on Bill Buxton's input-device timeline https://www.billbuxton.com/inputTimeline.html (which at least dates back to 2011 https://web.archive.org/web/20110410220530/http://billbuxton... ) but there's no citation to support it. Any ideas, anyone?
phire•2mo ago
Woz was almost certainly there when ADB was created. It's documented that he was quite involved in the design of the Apple IIGS. And ADB was created for the IIGS (right?)

But that doesn't quite mean he was involved in the design of ADB itself. And we know he isn't listed on the patents.

karlgkk•2mo ago
I’m not trying to be crass, but SW did very little engineering after 1981. By 1985, he was still openly struggling. He may have been involved in integration but it’s very unlikely that he “invented” adb.
djmips•2mo ago
Yeah that was a significant incident, the plane crash. I think we all know better how serious TBI can be.
