It was probably the board we did. We currently use it in our Intro.
to Architecture lab.. We run Minix on it so the students can edit
and assemble their programs and then load it into memory and use the
debugger in the monitor to actually run their code in standalone mode.

Unfortunately, you will have to have baught a copy of Minix-ST before
I can give out the bootdisks and sources, since Minix is owned by Prentice
Hall. I'm not sure how usefully it would be to make the sources to the
drivers I wrote available, since you can't really do anything with it
unless you have Minix.

Anyway, the schematics to this board are in :

	cs.indiana.edu:pub/goo/mc68030/schem

and the monitor souces/image in :

	cs.indiana.edu:pub/goo/mc68030/software

I'm also working on a NetBSD port for this system, but it's not quite
ready yet (the single user shell runs). This port is not based on the
Amiga and HP300 port, since my system is quite different and I wanted
to start from scratch to be able to really understand what's going on.
Also, I wanted to make this port a little more generic to make it easier
to port to other newer platforms.

Since it's not clear if our department will want to use BSD on these
machines I'm working on the port on my own time and get preempted by
real work. I will make an announcement when I have something running.
Probably, when the system can compile itself. The code should be usefull
for people that are doing their own 68030 (and possibly 68040) hardware
projects.
