With the release of the PB-100, Casio makes a step towards the real pocket computers. While the predecessor of the Casio PB series, the FX-720P, was still called a “calculator”, the PB-100 was now a personal computer. Models from this family, especially the first ones presented mediocre feature and were classified low-end to mid-range. Keyboard was reduced to absolutely minimum, maintaining the QWERTY style.
Of course later models showed more improvements, but regarding the RAM memory after the PB 300 there was none.
A notable feature for this brand line is the fact that Casio was the only manufacturer to combine a personal computer with an integrated printer. Furthermore, models included touch screen display.
That was just a snapshot on the presentation of the techmuseum series. Indulge more into the history. Continue reading more about the present model, the Casio PB 300 here. Alternatively, find more exciting stories like this here.
