I don't think page has been mentioned:
http://www.physics.brocku.ca/~edik/gpib/
There's a reference manual (254 pages!) for
a Nat. Semi. equivalent to the TMS9914.
I also have a copy of IEEE 488.2 somewhere,
email me if you think it mught be useful.
There's alo a GPIB FAQ around out there somewhere.
HTH,
Antonio
