Oh, this is really nice, thank you!

These boards, do they have some kind of digital or analog I/O for easy
interfacing?

Oops: Missed a tiny part of it. Sorry.

(*) I've tried the miniCodeROM patch for miniPicoLisp. While it works
like a charm on my GNU/Linux box, there's some more work left on the
AVR codebase before I can fully integrate it with Hempl. Hopefully,
very soon!
