Osborne I Portable Computer

The Osborne One portable computer is given its public debut at the West Coast Computer Faire in San Francisco. Despite being billed as “portable”, the computer is huge – packing 5¼” floppy disk drives and a tiny CRT monitor and a full-sized keyboard into a suitcase-sized enclosure, it weighs at least 30 pounds. The Osborne I’s native operating system is CP/M.
