Introduced at the West Coast Computer Faire in 1981, the Osborne-1 was the brain child of Adam Osborne, a computer columnist, writer, and engineer. It was co-developed with Lee Felsenstein, and Lee designed it. The goal was a truly integrated computer that could go wherever the user want to. The machine was shipped as a full package including all the hardware and software a user could need including: 64K RAM, Z-80 CPU, 5″ CRT, two floppy drives, keyboard, serial ports, CP/M operating system, WordStar, SuperCalc, and two versions of BASIC: CBASIC and MBASIC. The machine also had the ability to connect with scientific equipment via a built-in IEEE-488 interface, and could run an optional external monitor via the built-in port. Not only was the machine complete, it was cheap – $1795.
The Osborne weighed a hefty 24lbs. altogether. Try lugging that around an airport!
