Doug,
  A few years ago I got it to power on and it runs Unix
variant, their
 product name was Idris. I have 16 floppies (dated 1992) that came with
 the system, but the hard disk has died. 
Interesting! I have a Multibus system that runs Idris, very little information seems to be
around on it. Mine's a straight 68K.
  What are the minimum requirements for BSD? 
With an '030 you should be able to run NetBSD-CURRENT, slowly :P You would of course
have to write drivers for any unsupported hardware you need.
Thanks,
Jonathan
