  GPIB =
General-Purpose Interface Bus. Aka IEEE-488, and very similar to HPIB (=
Hewlett-Packard Interface bus). HP were the company who designed it,
but it turns up on all sorts of machines.

It's an 8-bit parallel interface using a 24 pin connector. 8 pins are ground,
8 are data, 3 are handshake, and 5 are bus control/management. It was
originally designed to link up lab equipment (DVMs, counters, digital 'scopes,
But also for interfacing Analytical Instruments (Spectrophotometers, Gas
Chromatography etc.) for chemical laboratory, where HP is still one of the
most important developing company, and where GPIB is still used.
