2.  Originally developed by HP in the 1960’s  Wanted an easier way to interface the instruments and controllers  Other companies started using it and named it the General Purpose Interface Bus  The device was standardized in 1975 by the IEEE and again in 1978 and 1987  IEEE 448.1 is the standard for the connector, while IEEE 488.2 is the control command standard

3.  Total of 24 pins on the device  8 pins for data, 8 for ground, 5 for bus management and 3 “handshake” pins  Connected devices can be talkers, listeners, or controllers  Wires are “double-headed” with a male connector on one side and female on the other

4.  Rugged connector that is screwed in place  Well established and supported by many devices  Fast and slow devices can be used in the same system

6.  Connector is large and bulky  Cable and connector are more expensive to make than others such as USB  Maximum transfer rate is around 8 Mbits/s  USB 3.0 can transfer at 5 Gbits/s  Not a standard connector on modern PCs
