Portable Pioneer Adam Osborne dead at 64

Posted by chrisd on from the heavy-news dept.

douglips writes "Yahoo News has the story. He's best remembered for the blunder of announcing that his next version of the Osborne portable computer was so much better, that nobody bought the current version and the company died quickly. I'm sure everyone in the Slashdot community will miss him - even if you didn't enjoy his work, there's no denying his contributions to popular culture. Truly an American icon."

    Writing the manuals for the Intel 4004, the very first single chip CPU.

    Rest in peace.

    Believe me, I'm as surprised by my comment as you are.

    The Osborne1 was the hot piece of technology. And to give you an idea how desperate the situation was, consider this.
    • It had a 5 inch screen that was monochrome (amber I seem to recall).
    • It weighed a freakin' ton. Okay maybe 30lbs. But the brochures highlighted that like it was impressive (Only 30 lbs!).
    • There were two 5.25" floppies (360k?)
    • 64 kB of RAM!
    • And last, but not least, a 4MHz Z80 CPU!

    Gadzooks how could one resist? But for a lot of folks who needed a computer not bolted to the floor (like reporters), the Osborne1 fit the bill.
  4. The computer that did Osborne in by mpthompson · · Score: 5, Informative

    For those interested, the Vixen is the system that was pre-announced and caused the demise of Osborne Computer due to the ensuing cash flow crunch.

    Having an Osborne 1 at the time and active in FOG I remember lusting over the Vixen. How times have changed...

  6. My first computer was an Osborne I by beej · · Score: 4, Informative
    Rather, my parents' first computer was. I learned to program it as a kid before moving on to the c64.

    POKE 61440, 127

    That'll put a dim rectangle in the upper left corner of the 52x24 screen. Too bad no one ever asks me that in an interview these days...

    As I sit here, I hold in my hand the Osborne I User's Reference Guide. I don't have the computer, but I kept the book for fun. It reads like an old school user's guide, with complete references for BASIC, and a chapter titled "IEEE-488 Implementation". Very useful for users.

    • 32 lines of 128 characters maintained in RAM
    • 24 lines of 52 characters shown on screen

    • 1024 bytes per sector
    • 40 logical sectors to CP/M (128 bytes each)

    • 3 reserved system tracks
    Single Density:

    IEEE-488 PORT:

    • standard IEEE-488 implementation

    I'll stop typing now before I get to the memory map... :)
