Acorn's range of 8-bit machines include the Atom (on the picture), the BBC
models A, B and B+, the Electron, the BBC Master
and the Master Compact.
Atom (1979) had 6502A/1 MHz CPU, 8 KB ROM (max. 16), 2 KB RAM (max. 12), 8 colors and 3 voices. A several peripherals were developped for it: e.q. 5,25" FDD or a network called EcoNet (this network allowed to link up to 250 Atoms).

The adventure started in 1981, when the British
Broadcasting Corporation (BBC) wanted to host a
series of programs introducing the British public to
computers. Acorn Computers Ltd. scooped the contract.
The first model, BBC model A (on the picture), was limited by 16 KB of RAM and tape-based, while the BBC model B doubled the amount of RAM and added a floppy drive or a network adaptor.

|The BBC B was quite expensive, so Acorn decided to produce a smaller, more limited "little brother", called Electron. As technology improved, Acorn introduced its "big brother", the BBC Master. It also came in several models: the Master 128 and 512 with 128 and 512 KB memory respectively.|
