The Osborne 1 computer was a portable computer introduced in 1981. While it cost $1,500, it came with the CP/M Operating System, and included a software bundle that Osborne claimed would cost around $2,000 if purchased separately.
The Osborne 1 was not IBM PC compatible, and so this computer vanished into history, along with many other popular CP/M-based computers.
