We got out of the HP 68k biz before th 98702 so I don't know a lot about
it.  Hmm...but come to think of it, it may have been a 98702 that came on
our first snake machine.  If that is the case, then at least some of the
support you need is in our Mach release.  We only used that interface in
"ITE mode" and replaced it before we started trying to map the framebuffer.

However, it supports STI (Standard Text Interface) and in theory should just
work with our Mach driver (including framebuffer mapping).  This of course
assumes that you can figure out how to load the STI code out of the ROM...

Assuming you get that all to work, you will have to run the HP-UX X server
since the one that Mark D. did doesn't support newer displays.  This shouldn't
be a big problem if you have HP-UX around somewhere.  We use the HP-UX X
server on our 4.3bsd/4.4bsd hp300s and the NetBSD HP-UX compat code is
pretty much the same.
