However, as this radical design failed in the marketplace, Intel also tried it on its more conventional 8086-family of processors, mainly used as a kind of system prefix but also to denote individual processors in the family. The 8086 based line was therefore called the <b>iAPX 86 series</b> for a few years during the early 1980s.<sup id="cite_ref-Intel_1983_iAPX286_2-1" class="reference"><a href="#cite_note-Intel_1983_iAPX286-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-i86_4-0" class="reference"><a href="#cite_note-i86-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> This was abandoned rather soon, however.
