A9home

The A9home is a niche small-form-factor desktop computer running RISC OS Adjust32. It was officially unveiled at the 2005 Wakefield Show, and is the second commercial ARM-based RISC OS computer to run a 32-bit version of RISC OS. When the Iyonix was withdrawn from sale, the A9home remained the only hardware to be manufactured specifically for the RISC OS marketplace.

It is smaller than the Mac mini and housed in cobalt-blue aluminium casing, measuring 168 mm × 103 mm × 53 mm in size. The machine runs on a 400 MHz Samsung ARM9 processor, has 128 MB SDRAM of main memory and 8 MB VRAM and houses an internal hard disk of 40 GB. On the front, it features two USB 1.1 ports, a microphone and a headphones socket. On the rear, it has two USB 1.1 ports, two PS/2 ports, 10/100 BaseT network port, a RS-232 serial port and a power connection socket. Like the Mac mini, it is powered by an external PSU (5 V, 20 W). Furthermore, it has a power/reset switch, a status/health indicator and a drive activity indicator LED. The A9home is not designed to be internally expanded.
