But the VIDPAL simplifies the access to the screen, making it very similiar
to a sun for the port. (Notice that MGR runs on Suns and 3b1's). Also, doing
a port would certainly give you experience in writing X code. And some of
the X terminals avaliable are 720*348 and cost around $1000. Without disk!

The port on the server should not take more than 2 man weeks of work. Hopefully
I'll get some more time soon to finish the X3b1 server in June.
