Apollo display driver code:

This is some hack code that I put together along with some work from Hamish
Coleman (hamish@zot.apana.org.au) to basically diddle the Apollo Mono
and 4/8 plane ISA-bus display cards.

The code has the ability to clear the screen, blit characters onto the screen,
and scroll the screen up.

There's a stupid main() stub there that does a bit of character I/O that's
pretty hacked to make it compile under Linux, and on a Sun 3/60.  People
will notice calls to init_2681() and such, to them I would say that that
is for some of my other code to read from the Apollo keyboard via SIO0.

I use the code to generate an RFC file that I can then boot from the MD using
"ex whatever". Hamish used it to work on a Mono display driver for XFree86.

Basically; I was just playing around.

The code is of little value to anyone so I don't care what happens to it. If
anyone manages to do anything interesting with it or makes it work better; I'd
appreciate having whatever they feel would be useful to me.

Who knows; maybe it'll turn into something someday. (Like an Apollo port of
NetBSD or something. haha)
