The world's first portable computer

The idea of a portable computer was postulated in 1968. It saw the light of day 13 years later. The Osborne 1 weighed around 12kg, had 64k RAM, a 12cm screen, ran the CP/M operating system and came with a number of programs, including SuperCalc, WordStar and MS Basic. It cost R18 000 at today's prices. Osborne filed for Chapter 11 bankruptcy two years later.
