Timex Corporation, best known for the production of clocks, watches, and other timepieces, attempted to enter the fledgling home computer market of the late 1970s and early 1980s with the Sinclair line.

See the Timex Sinclair 1000 page for an alternate discussion of this topic.

The first such model was the TS-1000. It came in an impressively small case for the time, but was behind the technology curve in terms of graphics and basic features. It was equipped with only 1K of RAM (upgradeable to 16K by attaching a relatively large module to the back). However, to make things worse, it had no sound and only black and white graphics. This provided an inexpensive solution for thrifty spenders to get a basic home computer system at the time. As time went on and the home computer price wars of the early 80s brought the industry to its knees, the sinclair line expanded to include many more features and to compete with the Commodore, Apple, TI, and Atari offerings. Unfortunately, Timex's computer division was one of the casualties of the 1983-1984 Computer and Video Game crash. In fact, many companies left the industry and the way was paved for the Macintosh and PC to dominate the market.
