Sinclair ZX81

The Sinclair ZX81 came from the genius of Clive Sinclair and his desire to bring computing to the masses. The ZX81 was a simple, rugged and very inexpensive computer sold both as an easy-to-build kit and as a fully assembled system.

This machine was not intended to serve any business functions. It was a home machine from the outset designed with the goal of making computing accessible.

Sinclair ZX81 docs

Pictured are the documents that this unit came with. In addition to those I have a metric ton of books and other documentation donated by Trenton Henry.
