Acorn's first home computer, the Atom, came with 2KB of RAM and 8KB of ROM, optional colour graphics, Basic, and a proper keyboard. With a kit price of £120 and a built price of £170, it didn't cost much more than the same keyboard sold as a stand-alone accessory for the earlier rack-based systems. A disk drive, costing twice the price of the computer, was not popular.
Introduced in 1980, the Atom (pictured) lasted until made redundant by the Electron in 1983 — but not before it had been given Acorn's first Econet networking system.
