There is already support for the CPU, host- and ISA-bridge in port prep.
All we need is some glue code to make this machine knowen to NetBSD.=20

OK. Interrupt routing trouble. Depending on the hardware there may be a
chance to get this solved quite quick.=20

I have done some work in that area of port-prep / port-ofppc, so I know
a bit what is going on. But I am no kernel hacking expert, I am still a
novice. (I still need to understand that interrupt handling stuff.) If
someone with "The Clue" can get access to this machine in an
developement environement it would be a matter of a few houres to get
NetBSD running. At the moment I can't help you further. Sorry. Maybe a
NetBSD kernel hacking guru is willing to volunteer and you can setup
some remote console access for him?=20

Hmm. Don't know how to trace this.=20
