That's what I'm hoping to do with the '286 Bridgeboard, though not
with SCO Xenix (Xenix is NASTY... I want something that's at least Sys
V.2 compatible, and doesn't cost an arm & a leg). As a bonus, the '286
card is likely to be cheaper than the 68020 board.

The CPU slot is nice as a cheap way of sliding in a 68K-compatible
processor to run AmigaDOS. But as a vehicle for Unix, it's somewhat
lacking. The ideal setup for Unix would be an '030 based card that sat
in an ordinary Zorro slot a' la' the Bridgeboard, with 4mb onboard,
that negotiated with the AmigaDOS half for I/O (perhaps via X window
system). This would allow you to use any AmigaDOS device without
needing a custom Unix driver from the manufacturer.
