The career of laptops began in the 90s of the twentieth century, however, the first laptop appeared in the late 70s. Alan Key, an employee of Xerox PARC, is considered to be the originator of the laptop concept, originally referred to as “Dynabook”. Unfortunately, the solution he proposed was not widespread. In 1979, Grid Compass Computer debuted on the market. Its creator was the British engineer William Moggridge, and the first recipient – the American space agency NASA, which used the equipment in the space shuttle program. The price of Grid was high and not everyone could afford to buy the device: the cost was from 8 to even 10 thousand dollars. The laptop contained 340 KB RAM, an Intel 8086 processor and a display with a resolution of 320 x 240 pixels. The Grid Compass Computer fit in the bag and was relatively light, weighing about 5 kg, and its housing was made of magnesium alloy. Grid also entered pop culture – in 1985 in the movie Perfect he was used by the hero played by John Travolta.
