But there were doubts about the validity of the patent - relating to the
three-wire handshake - on the grounds that it was obvious and any competent
engineer would have done it that way.
Most manufacturers of IEEE488-compatible equipment simply ignored the
patent and went ahead anyway. I never heard of any being sued by HP.

The hpib became the IEEE488 in 1973. No license was needed to use it.
You are correct in saying it was the only interface available for test
instruments. If you wanted to control a process with instruments,
especially from different manufacturers, you used the hpib.
It was a simple interface and easy to understand. You could design your
own interface using a subset of the available commands. Ziatech made a
very inexpensive interface tester that could be used as a monitor or
controller to debug the interface.

Casper,
Many have stated what it is, and how long it has been around, so there
is no need for me to state that.
What has not been stated is that it is still in common use on modern
(i.e. sold today) test equipment. On expensive equipment it will be
standard, on cheaper stuff usually an option, and on the very cheapest
test kit you will not find it.
You will not find it on a sub $100 digital volt meter, but it will be
pretty standard on a $1000 bench DVM for lab use.
It is in fact similar in many ways to SCSI
1) It has been around for ages.
2) Still very common.
3) Parallel bus
4) Multiple devices on the same bus
5) Each device has a unique address.
6) Just add cables to add another instrument.
7) There are limits of distance and number of instruments.
8) You can get extenders.
And GPIB boards are sold this day new of course.
So Sun supporting it might not be a bad idea.
PS, I am still looking for the drivers for Solaris, for my home Sun on a
home project to look at the drift of an quartz oscillator relative to a
rubidium standard, using an HP time-interval counter, so if anyone is
able to help, get in touch at:

And Motorola made the 68488 chip, which allowed a simple
microprocessor to become IEEE488 capable.
I first used it for controlling a Fluke high voltage power
supply from a computer, putting it between the Fluke's own wide
interface and the computer which needed to control the power supply (a
HP 9825 IIRC).
Later, I designed a controller for Diablo daisywheel printers to
allow some friends to connect them to their Commodore PETs, using the
68488 and a 6802 as the "smarts".
Enjoy,
DoN.

Somehow this jogged my memory, and I remember a Centronics connector -
like a parallel printer, but not as big. So, before making a public
fool of myself, I looked them up:
http://www.interfacebus.com/Design_GPIB_Mechanical.html
http://www.nullmodem.com/Centronics.htm
Oh, well, different number of pins. :-) And HPIB, of course, can
piggyback for daisy-chains. (I saw a training video once at Control
Data, where the lecturer mentioned daisy-chaining, and noted "Nobody
really wants to talk about where that particular term came from...")
Cheers!

Someone elsewhere provided this reference:
http://www.math.utah.edu/pub/tex/bib/hpj.html#Nelson:1972:PIS
which is a reference to a 1972 HP Journal Article by "G. E. Nelson and
D. W. Ricci"

well, National Instruments updated their drivers around 98/99 to support |
more "instruments/gpib-enet" devices, 128 i think it is.
