iyonix pc edit the iyonix pc codenamed tungsten was developed as a set top unit stu in secret by engineers at pace s shipley campus along with a 32 bit version of risc os 4 known as risc os 5 . when management discovered the project the campus was closed . 8 castle technology acquired the proposed designs and the original engineers from pace to further develop the tungsten into a desktop computer . robert sprowson the original hardware designer declined to join castle technology and so peter wild was recruited . 8 the iyonix pc was released six months later . although it was well received it was not designed for long term production and therefore used some components that were near obsolete when it was released . 8 a problem for the iyonix pc was that it used leaded components which were outlawed with the adoption of directive 2002 95 ec in february 2003 by the european union . however by this time castle technology was financially troubled and could not afforded to re engineer the iyonix pc without the leaded components . 8 the remaining iyonix stock were passed to iyonix limited which stopped distribution on 30 september 2008 . 9 divisions edit tematic edit in 2004 castle
