    Internet is the greatest thing... I've first heard about this machine almost a dozen years ago in the online museum of a japanese collector. There were a couple pictures, including a few screenshots where i could see the machine display a windowing GUI.
    Since then, i've never stopped wondering what the machine could be, and ultimately, i lost all hope in ever finding one.

    And then i eventually found one! It seems that the machine commercial distribution never spread outside the japanese ground, although there were plans for it to reach USA, as this page (archive from a '95 magazine) explains.

    What i know about the machine, however, didn't expand a lot since i got one. I basically learned more from the page above than from the scarse documentation (in japanese, thus i had to rely on pictures only!) i got with the device.
    My PA-100 is, as far as i know "not working", most likely because it would miss the necessary ROMs that would provide it with whichever OS/application it needs to run.

    Now, the machine comes under the "Business Execution Support Tool" brand. Casio did release quite a few regular (albeit higher-end) PDAs by that tag, so i am a little surprised that the PA-100 would need specific ROM packs to run. Then again, it could make sense, as i've learned in the same page that GEOS was also intended to be ported on the machine, so it would be realistic to assume that there was no "built in" OS or application, and the machine would offer a choice of flavors in the shape of ROMs pack of the user's choice.
    Now, why would this one come without a ROM pack is a mystery...

    Anyway. Apparently, Casio had high expectations for this little buddy. A nice design, interesting balance in computing power (resource-consuming handwritting recognition tasks were left to a dedicated processor, thus freeing the 8086 compatible main processor for other, application-oriented tasks), and high versatility (assuming the ROM pack guess proves right), all of this with Casio trademark low battery consumption that could have the machine running for weeks on simple AAA batteries.

    However, over a dozen years later, very few have heard of the PA-100 outside Japan. I, for one, am happy i have, and even more, i'm happy i finally got one!

    As a bonus, it came with this nice little wireless printer :
