The ZX81 is a home computer that was produced by Sinclair Research and manufactured in Dundee, Scotland, by Timex Corporation. It was launched in the United Kingdom in March 1981 as the successor to Sinclair's ZX80 and designed to be a low-cost introduction to home computing for the general public. It was hugely successful; more than 1.5 million units were sold. In the United States it was initially sold as the ZX-81 under licence by Timex. Timex later produced its own versions of the ZX81: the Timex Sinclair 1000 and Timex Sinclair 1500. Unauthorized ZX81 clones were produced in several countries.
The BallyAstrocade is a second-generation home video game console and simple computer system designed by a team at Midway, at that time the videogame division of Bally. It was originally announced as the "Bally Home Library Computer" in October 1977 and initially made available for mail order in December 1977. But due to production delays, the units were first released to stores in April 1978 and its branding changed to "Bally Professional Arcade". It was marketed only for a limited time before Bally decided to exit the market. The rights were later picked up by a third-party company, who re-released it and sold it until around 1984. The Astrocade is particularly notable for its very powerful graphics capabilities for the time of release, and for the difficulty in accessing those capabilities.

The ActionNote was a series of notebook-sized laptops developed by Epson America in 1993. The series was Epson's answer to the small businesses and home office market for laptops and initially ran alongside their corporate-oriented NB series of laptops. The series was segmented into premium and low-cost offerings and included a subnotebook, the ActionNote 4000. The bulk of the laptops' manufacturing was performed by ASE Technologies of Taiwan, with the exception of the 650 and 660 series, which were produced by Compal, and the short-lived initial entries into the 700 series, which were produced by Jabil Circuit. The ActionNote received mixed, mostly positive, reception in its lifespan before Epson America silently left the personal computer market in 1996.
