So after doing many test boots I've found netbsd 1.5.x will boot on it
but everything else, including sunos 4.1.1, will fail in various ways.
The fact that even sunos doesn't work on it leads me to suspect that
this is bad hardware. A shame since these boards are getting rare
these days. If anyone has suggestions I'm all ears and sorry for the
noise.
