The Iyonix PC was sold by Castle Technology and Iyonix Ltd from 2002. It used standard PC-compatible hardware but ran RISC OS 5 (developed from source code licensed by Pace for set-top boxes). Development of the Iyonix PC was initially carried out in secret under the codename Tungsten. The Iyonix was the first major redesign of the RISC OS platform since the RISC PC was introduced in 1993.

The Iyonix had PCI and USB expansion ability, and also kept the ability to use the legacy "podule" cards. Unlike Acorn's Phoebe machine, no attempt was made to retain compatibility with VIDC or 26-bit mode. The Iyonix is believed to be the first shipping computer to use Intel's XScale processor.

Production of the Iyonix PC ceased in 2006 following the introduction of RoHS regulations. Castle Technologies stopped taking orders for the Iyonix on 25 September 2008.

Our Iyonix PC is complete with original box, keyboard, and manuals. It has serial number IY01100939.
