Sun has addon Sbus cards which contain (e.g.) a 486 processor.
That CPU runs DOS. Things are setup so that when it tries to write
on the VGA it ends up writing on the GX frame buffer. These cards
are said to be extremely good, though I don't know anyone who would
want to run DOS after having a Sun.
There is also available an AT-bus card with a sparc2 (40 Mhz) on it.
It does similar things. See the July BYTE for details (well, at least
more info...)
