Its enhanced video capabilities allowed the A5000 to comfortably display VGA resolutions of up to 800×600 pixels. It featured the new 25 MHz ARM3 processor, 2 or 4 MB of RAM, either a 40 MB or an 80 MB hard drive and a more conventional two-part case. The new model only sported a single expansion slot, which was physically different from that of the earlier models, although electrically similar. This kind of housing consumes a lot of desktop space, a problem that Acorn tried to overcome by offering a monitor stand that attached to the base unit. Unlike the previous models, the A3000 came in a single-part case similar to the Amiga 500 and Atari ST computers, with the keyboard integrated in the base unit. The A3000 used an 8 MHz ARM2 and was supplied with 1 MB of RAM. The earlier models could be upgraded to RISC OS 2 by replacing the ROM chips containing the operating system.

A number of new machines were introduced along with it, and in May 1989 the 300 series was phased out in favour of the new Acorn A3000 (the 400 series was kept in production).

Work began on a successor to the Arthur operating system, initially named Arthur 2, but with the release of the Hollywood movie of the same name it was renamed to RISC OS 2. The 300 and 400 were followed by a number of machines with minor changes and upgrades: All models featured on-board 8 channel stereo sound and were capable of displaying 256 colours on screen.įour models were initially released with different amounts of memory, the A305, A310, A410 and A440. Both models included the Arthur OS (later called RISC OS), BBC BASIC and an emulator for Acorn's earlier BBC Micro, and were mounted in two-part cases with a small central unit, monitor on top, and a separate keyboard and three-button mouse. The 400 series included 4 expansion slots (although a 2 slot backplane could be added to the 300 series as an official upgrade, and third parties produced their own 4 slot backplanes) and an ST506 controller for an internal hard drive. The first models were released in June 1987, as the 300 and 400 series. The BBC Computer Literacy Project 'Owl' appeared on the keyboard, above the function keys on the Archimedes 300 series and A3000 keyboards.
