Access.bus

A serial communications protocol developed by Philips Semiconductors and Digital Equipment (DEC) in 1985 for connecting peripheral devices to a computer. Access.bus is designed for hassle-free installation and configuration of relatively low-speed devices, such as keyboards, monitors, and printers. Access.bus uses a bus topology, which enables it to support up to 125 devices.

A competing standard, Universal Serial Bus (USB), is quickly becoming the serial standard of the future.
