Thanks. I'll check out the Amiga ones. Pretty interesting machine, and I'd read earlier, very advanced for its time. IIRC, one of the designers of either the hardware or OS of the Amiga, also later designed the REBOL language - Carl Sassenrath. I've tried out REBOL a bit, and it's interesting, with what seems to be a somewhat different approach from many other languages. It recently got open sourced.
