The Acorn A5000 was an all new model of the Archimedes family replacing the A540. It had 4 slots like previous models but a larger wider case making it look like a workstation computer.

In 1991, the A5000 was launched. 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. Its enhanced video capabilities allowed the A5000 to comfortably display VGA resolutions of up to 800×600 pixels. It was the first Archimedes to feature a High Density capable floppy disc drive as standard. This supported various formats including DOS and Atari discs. A later version of the A5000 featured a 33 MHz ARM3, 4 or 8 MB of RAM, an 80 or 120 MB hard drive and a revised OS (RISC OS 3.10).

The A5000 ran the new 3.0 version of RISC OS 3.0. As previously, earlier machines were capable of being upgraded to the new RISC OS 3, though some needed help, as well as the ARM3 CPU. Earlier models could also benefit from the video performance of the A5000 via a third party upgrade.

A5000 ALB55 and has a daughter board upgrade attached to the processor slot.
