IEEE-488 is a short-range digital communication 8-bit parallel multi-master interface bus specification. IEEE-488 was created as HP-IB (Hewlett-Packard Interface Bus) and is commonly called GPIB (General Purpose Interface Bus). It has been the subject of several standards.

Although originally 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 still sees some use in the test equipment field.sai.
