Steve,
Did you know that DELL has a 486 PC with GRASS loaded on it?
They've arleady done all the work of porting and compiling.
The pc runs Unix system V, version 4. It behaves just like
a Sun workstation. If you're interested, I can find some
names and phone numbers for you.

p.s. it just occurred to me that you might want
to do the porting yourself???
