The plan is to run Linux or NetBSD on the S-100

would also be running the X window server.
If you go NetBSD: There are the wsfb(4)
X-Server and the wsdisplay(4) /
fbdev(4) frame buffer driver. I.e. if you write a kernel level framebuffer for your hardware, the X-Server will work out of the
box. Unaccelerated of
course. A wsdisplay(4) / fbdev(4) driver should be relatively simple. It
will also
solve the problem of text mode IO on a non-VGA
console. So you are
completely free to implement what ever graphics / framebuffer hardware you
want. There is no need for a VGA compatible register set.

Hi
Thank you. That's very good news since if we can keep the changes isolated
to a kernel module maybe with some luck we can minimize the changes to the
rest of the NetBSD system. No changes at all would be ideal but is probably
not realistic. The S-100 80386 CPU board itself and the associated IO
hardware will likely require some of its own modules and changes.
Thanks and have a nice day!
