We never had a 715/33 so I don't know anything about them.  But someone
else said they had the ASP which is the "original snakes" IO subsystem
(705/710/720/730/750).  The ASP is quite similar to the LASI, and there
is plenty of code in the Mach sources.

Hit your HP sources up for:

	Corba/Coral I/O Subsystem External Reference Specification

Don't have a part or drawing number unfortunately.  We have version 1.43
from November 1990.  Looks like it came out of Cupertino.

As for the SCSI controller, the 700 isn't that different from the 710.
Had a few bugs though as I recall and our driver/script did not work
around all of them.
