Sinclair ZX80 Weight and Key Specifications

The Sinclair ZX80 was a groundbreaking home computer released in 1980 that brought computing to the masses. This article explores the history of the ZX80, its technical specifications, and physical attributes, including the specific weight of the unit. Readers will gain insight into why this machine remains a significant piece of computing history.

Historical Context

Launched by Sinclair Research in the United Kingdom, the ZX80 was designed by Jim Westwood. It is widely recognized as the first computer available in the UK for under £100. This price point democratized access to technology, allowing hobbyists and families to experiment with programming and BASIC for the first time. The machine came in two forms: a kit for enthusiasts to assemble themselves and a pre-assembled unit for general consumers.

Physical Specifications and Weight

One of the most remarkable features of the Sinclair ZX80 was its compact and lightweight design. The unit was housed in a small white plastic case with a membrane keyboard. Regarding the specific inquiry about its mass, the approximate weight of the Sinclair ZX80 unit was 350 grams (0.77 lbs). This incredibly light build made it highly portable by the standards of the era, though it required an external power supply and a television set to function as a complete system.

Technical Features

Inside the lightweight casing, the ZX80 featured a Zilog Z80 processor running at 3.25 MHz. It came with 1 KB of RAM, which was expandable to 16 KB. The system outputted black and white graphics to a standard television set via a UHF modulator. Despite its limited memory and monochrome display, it was capable of running BASIC programs and simple games, serving as the foundation for the subsequent and even more popular Sinclair ZX81.

Legacy

The ZX80 paved the way for the British home computer boom of the 1980s. Its low cost and minimalistic design proved that there was a vast market for personal computing. While modern devices weigh significantly more due to larger batteries and screens, the ZX80 remains a testament to efficient engineering. Collectors today prize the unit not just for its historical importance, but for its unique place as one of the lightest computers ever manufactured.
