The tiny computer you see above originated in the UK as the Sinclair ZX81, a wildly successful build-it-yourself kit computer. Due to strong sales, Timex struck a deal with Sinclair to market a fully assembled version of the ZX81 in the United States. They rechristened the unit "Timex-Sinclair 1000," and the minuscule wedge became the first PC to sell for under $100 (US) fully assembled.
The diminutive, Z80-based 1000 was severely limited in function by its tiny membrane keyboard, its black & white display, no sound capabilities, and only 2K RAM. Despite that, it sold well in the US thanks to an incredibly low price. These days, Timex-Sinclair 1000s are relatively easy to find, and thanks to their nice shape, they make great doorstops.
