Any of the deskside 400's (and most 300's) will support multiple graphics
heads; you just put the interface card into any available DIOII slot.
We've done several combinations of 98731's, 05's, and 36's on a 433.
It's not a perfect setup though.  There's still only one hil loop
(i.e., 1 keyboard) per cpu, so only 1 graphics head can be used interactively,
say, for running X.  Other heads on the system can only be used as graphics
output devices.   If you want to support multiple "X-stations" on a single HP
cpu, you'll have to go w/ s800 machines.  The 825/835 machines will support
1-4 displays, each w/ its own hil loop.
