We need a victim (cough... volunteer) to work on the xy driver.
The work will require access to a Sun3 with an SMD disk and a
server that it can use to boot in diskless mode.

I have a manual for the Xylogics 450 controller which I will
copy for anyone willing to work on the driver.  You should be
able to use the Sprite driver as an example.  The source for
it is in the osrc.tar.gz file as sprite/dev/devXylogics450.c

Anybody interested?
