    Osborne 1, the first portable computer

    Released in 1981 by the Osborne Computer Corporation, the Osborne 1 is considered to be the first true portable computer - it closes-up for protection, and has a carrying handle. It even has an optional battery pack, so it doesn't have to plugged into the AC outlet for power. It was the beginning of Laptop Computer.

    Ports: parallel / IEEE-488
    modem / serial port

    I remember seeing one of those carried around by a guy in a suit, and we all crowded around him to marvel at those tiny green characters you could barely read. Wow, thanks for the flashback.

    I think it has letters, the photo just doesn't show them. Even Commodore had one of those and in the mid 80's it got a color monitor if I am remembering correctly. We (my friends and I) thought it was the coolest thing in the world. We talked about the day we would have one that was even more portable!

    EDIT: had to go find it and here it is:

    It's amazing how fast computer has evolved, the 80s is not so distance away, but the thing sure looked like it's from the 60s era LOL

    This remind me of old mobile phone:

    I remember machines like the Osborne in the computer shops and was hoping that I would own one one day.

    The SX-64 is an interesting machine I didn't know it existed but would probably have sold my grandmother for that if I had the chance.
