Designed by Lee Felsenstien and Adam Osborne, to be an integrated and portable computer. The machine came with several useful business software packages. Although they could not make enough units to keep up with demand, Osborne went bankrupt on 13th September 1983 due to the press breaking a nondisclosure agreement and leaking information about future developments - the Executive and the Vixen. The Executive was an enhanced model with an 80 column display, double density floppy drives and an optional hard drive. The Vixen was a smaller Osborne 1. People stopped buying the Osborne 1 because the enhanced machine was due to come out, but the Executive was late to market.
