I think that's the one I was working on, back about then. I got a
driver written, and it sort-of worked, but it was doing really bizarre
things I couldn't explain. (Doing one-sector reads of sectors 0 and 1
gave different results from doing a two-sector read starting with
sector 0, that's the flavor - but none of the reasonably simple
explanations I came up with matched the behaviour I saw; I never did
figure out what was going on. I was working remotely, which may or may
not be part of why I never figured it out.)

Me? Nothing, though I *am* rather tempted to try to track down a Qbus
interface chipset, some devel pcbs, and take on the task myself.
