BBC Model A
Launched in 1981 to coincide with a computer literacy drive by the BBC, the Model A was the cheaper of Acorn's two machines at £299. The machine's high cost was compensated for by very impressive expansion possibilities including disc drives, a second processor and network capabilities (Econet).

The Acorn BBC model A was the successor of the Acorn Atom was originally known called the Acorn Proton. It was a very popular computer in the UK and was widely used in schools, but it didn't have great success elsewhere (even though it did have great features, it was too expensive).
This computer got its name because in 1980, the BBC decided to start a computer literacy television series. The network realized that, with more powerful and increasingly inexpensive microcomputers, it would soon be possible to create them with enough computing power to offer their owners personal hands-on experience with microcomputers at an affordable price.
The BBC considered the NewBrain computer and rejected it. Acorn and Sinclair Research, along with other companies, then submitted designs, and Acorn won. The BBC Micro was then used almost universally in British schools from its birth into the 90's.
It was followed in 1982 by the Acorn BBC model B. The Model B had the same features but had 32 KB RAM (expandable to 64K). One of its most popular peripherals was the "Torch" floppy disk unit, a 5.25" floppy disk drive with a Z80 which allowed the BBC to use CP/M software. Acorn also made a cheaper version of the BBC (fewer connectors & video modes) called Acorn Electron.
