The Happy-Hacking ADB keyboard for one (just looked at the web page, was
the first that came to mind).

I'm not sure about apple designed keyboards besides those on the Mac+ and
like machines (non-adb). All the ones I've seen - FrogDesign/IIGS, Apple
Extended II, AppleDesign, Apple Adjustable, etc - have it. I haven't seen
an Apple Extended I or a non-extended (was there one?) for years, so I
can't say about those ones.

Ah, ok. Wasn't sure about that.

Very nice idea.

...hopefully defaulted to the standard Alt-f13/printscreen/sysrq-key in the
absense of the kernel commandline.
