Two Q1 microcomputers, widely considered to be the first single-microchip PCs, have been found by house clearers in the U.K. The discovery brings the total number of known surviving units to three in the world.
Employees from the house-clearing company Just Clear found the two Q1s buried under several boxes while clearing out a property on Dec. 18, Just Clear's founder Brendan O'Shea told Live Science in an email. These two models were last used by an oil drilling company in the 1970s, and the other known model's location is thought to be somewhere in Scandinavia, O'Shea added.
