The MicroDigital Mico has a 56MHz ARM7500FE CPU, 16MB RAM and a 6.4GB Hard disc. It had 1 parallel and 2 serial ports, joystick/MIDI port, sound sampler ports and 3 internal Microbus and 2 ISA expansion slots. It could optionally be fitted with a CD-ROM and an internal modem. A "Lightning" graphics card could be fitted to give 1600x1200 in 24 million colours. It ran a version of RISC OS 4.03 configured for the Mico. The Mico was available in desktop or mini-tower configuration.

The Microdigital Mico was designed in the post-Acorn world and launched in 1999. It was based on the ARM 7500 chip and a Microdigital designed motherboard. It is very similar to the RiscStation R7500 (apart from the motherboard). I bought my Mico from APDL in June 2004. It was a special offer, ex-demo, system.
