The Sinclair ZX81 home computer, released by Sinclair Research in 1981, was the follow up to the company's ZX80. The case was black, with a membrane keyboard; the machine's distinctive appearance was the work of industrial designer Rick Dickinson. Video output, as in the ZX80, was to a television set, and saving and loading programs was via an ordinary home audio tape recorder to magnetic audio tapes. It was very significant historically because it was the first home computer under $100 USD (in kit form), and therefore was a big volume seller. A US-only version was produced by Timex as the "Timex Sinclair 1000".

@ProfPing Yes he was, I loved the whole thing as I had a ZX81 and then an Acorn Electron when I was a nipper

@nzlemming ha, no. ZX81 ASCI art was my early foray into the digital world. Didn't play with comps until about time of Quarda, own a SE.

@SubEWL @r38y the ZX81 is kind of hard to see in that engraving you sent. Maybe it's behind the mallet?

@SubEWL @r38y they put in champagne corks with a Sinclair ZX81? Man, that is *much* better than my boring ol' Google results.
