Appreciate the suggestion. Do you have any pointers to available VME stuff
along these lines I could look at? Of course I would prefer to use SunOS,
but older versions of NetBSD are also perfectly acceptable as well. Some
time ago I thought about picking up an old Amiga and upgrading the CPU on
it to a 68060 and then running NetBSD, but the Amiga collectors are bidding
up the prices on them to more than I'm willing to pay for a vintage
computer put together as cheaply as was feasible at the time.
