An interface chip between 53c720 and HPs internal GSC bus.  In my case
the Zalon chip is on a GSC card called Bluefish.

http://puffin.external.hp.com/parisc/hp9000_models.html shows hardball
as the project name for 735 machines.

http://216.208.98.4/view.php3?type=machine&name=735%2F99 shows outfield as the
main i/o control for the machine.

I'd say LASI was a newer Outfield.  LASI gives you 53c710 scsi rather
than 53700.  Outfield gives you 82596 LAN, whereas my B180 with LASI has
a Dino (GSCtoPCI bridge) and provides Tulip LAN that way.

Of course, I'm not that well up on HP internals, so hopefully an HP
person will correct anything I got wrong.
