    I had a PB-1000 in my pocket during almost all my high-school years, and i liked the machine very much. Of course i still own it in my collection today, and i've even had occasions of acquiring a few extra models. As i got into collecting, i also had the chance of getting "legendary" PB-1000 related items. Here, "legendary" either means that they were items i could not afford back then, or that i had only heard rumors that i thought i could never verify.
    Amongst the rumors was the existence of a non-foldable "PB-2000" machine. Myth or reality? You can now discover by yourself in my collection!

    Quite a few years later, i've discovered much more, well beyond any rumor that could have come to my knowledge at the time. The PB-1000 family consists of 4 models, not just one as i was thinking at first, not even 2 as rumors had it. And i now own them all! Besides the PB-1000 and the PB-2000, the AI-1000 is directly related to the family despite it's "AI" reference. It uses the exact same platform as the PB-2000 including the ROM cartridges port allowing for the same optionnal to be run on the device. Then there's the PB-1000C, of which i've discovered about the latest.

    After this quite long introduction, what should be said about the PB-1000C? Basically, it uses the exact same platform as the PB-1000 : same foldable casing, touch screen, and so on. Also uses the exact same Basic, and the virtual disk memory like the others. Now what the "C" stands for is "CASL". CASL is a programming languages that replaces Assembly in the PB-1000C. The PB-1000 already offered 2 programming languages (C and assembly), and Casio expanded the multi-language features on the PB-2000 and AI-1000 by offering optionnal language modules and different built-in languages. The PB-1000C is thus a new step in these language evolution. The CASL language will later be re-used in more pocket computers from Casio (if not most of them), most of which will apparently never be distributed outside Japan.

    Rough Babelfish translations are also very interesting (for instance, i finally learned from this page that "PB" stands for "Pocket Basic" !)
