On the bright side, S-Video cables (4-pin Mini-DIN) work
just fine, though they don't usually come in the nice
"curly" form. You can usually get them quite a bit
longer, though; I don't know what the maximum length of
ADB is, but I suspect you could get at least a few
meters out of it.

Always wondered if that was the case. I've got plenty of ADB
keyboards lacking cables and plenty of S-Video cables. So both ADB
and SVid are wired straight-through?

Yeah, ADB wouldn't work any other way (it's an open-collector
shared bus, so the serial data pin needs to be the same on
every plug).

Yes, but there is a Gotcha.
The apple cable puts 4 separate signals on the 4 pins -- I think it's
power, grounds, serial data and the on-button. An S video cable has 2
signals (luma and chroma) and 2 grounds. It's not unheard-of for S-vido
cables to have the ground connected together, in which case they cause
ADB syutemns to think the power button is held down (IIRC).

That wouldn't surprise me terribly much, actually, but I've
been lucky enough to only use properly-wired S-Video cables
(each ground is supposed to be a separate signal return for
its corresponding signal. I can definitely imagine some
cheap cables tying them together at the plug ends. You'd
lose some of the video quality, but that's seldom mattered
much to unscrupulous cable manufacturers.

Yeah, I've used a few of those over the years. Work a treat. Can also
be used as ADB extension cables, handily.
