The Osborne 1 is the first commercially successful portable microcomputer, released on April 3, 1981 by Osborne Computer Corporation.[1] It weighs 10.7 kg (24.5 lb), cost US$1,795, and runs the CP/M 2.2 operating system. It is powered from a wall socket, as it has no on-board battery, but it is still classed as a portable device since it can be hand-carried when packed.
