<h2 id="history">History</h2> <p class="note">See also: <a href="/facts/Acorn_Computers/jCddUElC">Acorn Computers</a></p> <p>After Acorn withdrew from the <a href="/facts/Desktop_computer/edFPINdK">desktop computer</a> industry in 1998, Castle Technology acquired the rights to produce the <a href="/facts/Acorn_A7000/9N8CFJXV">A7000</a>, <a href="/facts/Acorn_A7000/9N8CFJXV">A7000+</a> and <a href="/facts/RiscPC/82A6RIzn">RISC PC</a> using the <i>Acorn</i> brand.<a class="footnote-ref" id="fnref:7" href="#fn:7"><sup>7</sup></a> </p><p>In 2001, development started on the <a href="/facts/Iyonix_PC/XJdlAzqe">Iyonix PC</a> (codenamed <i>Tungsten</i>) as a <a href="/facts/Set-top_box/hAsUsw67">set-top unit</a> (STU) in secret by engineers at <a href="/facts/Pace_plc/NuGasPcu">Pace's</a> Shipley campus along with a <a href="/facts/32-bit/TDMVce8s">32-bit</a> version of <a href="/facts/RISC_OS/Pc96teso">RISC OS 4</a> (known as RISC OS 5). When management discovered the project the campus was closed.<a class="footnote-ref" id="fnref:8" href="#fn:8"><sup>8</sup></a> </p><p>Castle Technology acquired the proposed designs and the original engineers from Pace to further develop the Tungsten into a <a href="/facts/Desktop_computer/edFPINdK">desktop computer</a>. Robert Sprowson, the original hardware designer, declined to join Castle Technology and so Peter Wild was recruited.<a class="footnote-ref" id="fnref:9" href="#fn:9"><sup>9</sup></a> 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.<a class="footnote-ref" id="fnref:10" href="#fn:10"><sup>10</sup></a> </p><p>A problem for the Iyonix PC was that it used <a href="/facts/Lead/EYljasJN">leaded</a> components which were outlawed with the adoption of <a href="/facts/Restriction_of_Hazardous_Substances_Directive/VbhtCJ1k">Directive 2002–95/EC</a> in February 2003 by the <a href="/facts/European_Union/6GYcR8qM">European Union</a>. However, by this time Castle Technology was financially troubled and could not afford to re-engineer the Iyonix PC without the leaded components.<a class="footnote-ref" id="fnref:11" href="#fn:11"><sup>11</sup></a> The remaining Iyonix stock were passed to Iyonix Limited which stopped distribution on 30 September 2008.<a class="footnote-ref" id="fnref:12" href="#fn:12"><sup>12</sup></a> </p><p>In 2004, Castle Technology acquired Tematic to further development of <a href="/facts/RISC_OS/Pc96teso">RISC OS</a> in <a href="/facts/Embedded_system/a4muX1wU">embedded systems</a>.<a class="footnote-ref" id="fnref:13" href="#fn:13"><sup>13</sup></a> In December 2005, Castle Technology moved its main office to the former premises of its <a href="/facts/Software_development/UUfsAaYY">software development</a> division,<a class="footnote-ref" id="fnref:14" href="#fn:14"><sup>14</sup></a> following the migration of Tematic to a neighbouring premises in Signet Court, <a href="/facts/Cambridge/gNRdbmwK">Cambridge</a>.<a class="footnote-ref" id="fnref:15" href="#fn:15"><sup>15</sup></a> </p><p>In 2018 RISC OS Developments acquired Castle Technology Ltd including the Intellectual Property.<a class="footnote-ref" id="fnref:16" href="#fn:16"><sup>16</sup></a> </p> <h2 id="external-links">External links</h2> <ul><li><a href="http://castle-technology.co.uk">Official website</a> </li></ul> <h2 id="references">References</h2> <ol> <li id="fn:1"><p>Bailey, Alasdair (May 2000).
