The BBC Microcomputer System, or BBC Micro, was a series of microcomputers and associated peripherals designed and built by Acorn Computers Ltd, for the BBC Computer Literacy Project operated by the British Broadcasting Corporation. Designed with an emphasis on education it was notable for its ruggedness, expandability and the quality of its operating system.

The machine included a number of extra I/O interfaces: serial and parallel printer ports; an 8-bit general purpose digital I/O port; a port offering four analogue inputs, a light pen input, and switch inputs; and an expansion connector (the "1 MHz bus") that enabled other hardware to be connected. Extra ROMs could be fitted (four on the PCB or sixteen with expansion hardware) and accessed via paged memory. An Econet network interface and a disk drive interface were available as options; all motherboards had space for the electronic components, but Econet was rarely fitted. Additionally, an Acorn proprietary interface called the "Tube" allowed a second processor to be added; several types of processor were offered by Acorn including 68000 versions. It was later used in third-party add-ons, including a Zilog Z80 board and disk drive that allowed the BBC machine to run CP/M programs.

A great old machine. Very powerful for it's day. My folks bought one or xmas one year, and my father got a massive £50 rebate on it, as he was a BBC Producer. The whole machine probably cost in the region of £200-250, plus a portable TV and cassette recorder, so that was actually a pretty god deal.
