The '''Timex Sinclair 1000''' (or '''T/S 1000''') was the first computer produced by [[Timex Sinclair]], a joint venture between [[Timex Group USA|Timex Corporation]] and [[Sinclair Research]]. It was launched in July 1982, with a US sales price of US$99.95, making it the cheapest [[home computer]] at the time; it was advertised as "the first computer under $100".<ref>{{Cite news |date=April 22, 1982 |title=Timex Corp.

As purchased, the T/S 1000 was fully assembled and ready to be plugged into home televisions, which served as a video monitor. The T/S 1000 was a slightly modified version of the [[Sinclair ZX81]] with an [[NTSC]] [[RF modulator]], for use with North American TVs, instead of [[PAL]] for European TVs. The T/S 1000 doubled the onboard [[random-access memory|RAM]] from 1 KB to 2&nbsp;KB; further expandable by 16&nbsp;KB through the cartridge port. The T/S 1000's casing had slightly more internal shielding but remained the same as Sinclair's, including the [[membrane keyboard]], which had modified nomenclature to suit American tastes (e.g. "DELETE" instead of "RUBOUT") Just like the ZX81, the T/S 1000 had black-and-white graphics and no sound.

It was followed in 1983 by an improved version, the '''Timex Sinclair 1500''' (or '''T/S 1500''') which incorporated the 16&nbsp;KB RAM expansion and featured a lower price (US$80). However, the T/S 1500 did not achieve market success, given that by this time the marketplace was dominated by Commodore, [[TRS-80|Radio Shack]], Atari and Apple.
