Launched in October 1985, the ''T414'' employed the equivalent of 900,000 transistors and was fabricated with a {{nowrap|1.5 micrometre}} feature size. It was a 32-bit design, able to process 32-bit units of data and to address up to 4&nbsp;GB of main memory.<ref name="newscientist19860320_inmos">{{ cite magazine | url=https://archive.org/details/bub_gb_MZjobjexWkcC/page/n46/mode/1up | title=New chip displays its powers | magazine=New Scientist | date=20 March 1986 | access-date=22 June 2022 | last1=Anning | first1=Nick | last2=Hebditch | first2=David | pages=43–46 }}</ref> Originally, the first 32-bit variant was to be the ''T424'', but fabrication difficulties meant that this was redesigned as the T414 with 2&nbsp;KB on-board RAM instead of the intended 4&nbsp;KB. The T414 was available in 15 and 20&nbsp;MHz varieties. The RAM was later reinstated to 4&nbsp;KB on the ''T425'' (in 20, 25, and 30&nbsp;MHz varieties), which also added the <samp>J 0</samp> breakpoint support and extra T800 instructions. The ''T400'', released in September 1989, was a low-cost 20&nbsp;MHz T425 derivative with 2&nbsp;KB and two instead of four links, intended for the [[embedded system]]s market.
