    Definitely anchored in the 70's with it's massive round plastic design and fluorescent LED bar display; the CQ-1 may seem quite simple and just remotely related to most of the devices i gather in my collection.
    Definitely this is not a large-screen programmable machine. Not even does it have alphanumeric display or any kind of user-available memory. But my collections also focuses on pionneering machines, and the CQ-1 is one of these!
    What makes it a pionneer is actually not much; yet it makes the little device an important milestone. Electrically autonomous calculators existed prior to the CQ-1. Non autonomous multi-featured calculators also existed priori to the CQ-1. What makes the CQ-1 different is that it is the first autonomous multi-feature calculator!
    Think convergence... It seems obvious today that a PDA should include a built-in clock, a calendar, and even a calculator accessory. Well there had to be a first step, a pioneer offering several computer-controlled features in a single device... step forward CQ-1!

    Casio FX-190 : weird hybrid calculator. Definitely another Casio pionneer, maybe not that much of a milestone though.

    Casio PF-8000 : said to be the first consumer character-recognition databank calculator.

    Casio IF-8000 : first touch-screen PDA

    Ricoh RDC-I700 : communicant digital camera well ahead of it's time

    Sharp MI-10 Color Zaurus : first color display PDA (also with imaging abilities)

    Hewlett-Packard Omnigo 100 : two-modes PDA with foldable keyboard long before Tablet PCs

    Palm Pilot 5000 : this list could not be complete without the machine that revived the PDA market; and had everyone use the word "a palm" instead of "a PDA"
