IEEE 488
<hardware, standard> (GPIB, General-Purpose Interface Bus,
HP-IB, Hewlett-Packard Interface Bus) An 8-bit parallel bus
common on test equipment.
The IEEE-488 standard was proposed by Hewlett-Packard in the
late 1970s and has undergone a couple of revisions. HP
documentation (including data sheets and manuals) calls it
HP-IB, or Hewlett-Packard Interface Bus.
It allows up to 15 intelligent devices to share a single bus,
with the slowest device participating in the control and data
transfer handshakes to drive the speed of the transaction.
The maximum data rate is about one megabit per second.
Other standards committees have adopted HP-IB (American
Standards Institute with ANSI Standard MC 1.1 and
International Electro-technical Commission with IEC
Publication 625-1).
To paraphrase from the HP 1989 Test & Measurement Catalog (the
50th Anniversary version): The HP-IB has a party-line
structure wherein all devices on the bus are connected in
parallel. The 16 signal lines within the passive
interconnecting HP-IB (IEEE-488) cable are grouped into three
clusters according to their functions (Data Bus, Data Byte
Transfer Control Bus, General Interface Management Bus).
In June 1987 the IEEE approved a new standard for programmable
instruments called IEEE Std. 488.2-1987 Codes, Formats,
Protocols, and Common Commands. It works with the IEEE
Standard Digital Interface for Programmable Instrumentation,
IEEE 488-1978 (now 488.1). HP-IB is Hewlett-Packard's
implementation of IEEE 488.1.

IEEE-488
IEEE 488 is a short-range digital communications 8-bit parallel multi-master interface bus specification developed by Hewlett-Packard as HP-IB (Hewlett-Packard Interface Bus). It subsequently became the subject of several standards, and is generically known as GPIB (General Purpose Interface Bus).
Although the bus was created in the late 1960s to connect together automated test equipment, it also had some success during the 1970s and 1980s as a peripheral bus for early microcomputers, notably the Commodore PET. Newer standards have largely replaced IEEE 488 for computer use, but it is still used by some test equipment.
