Casio Cassiopeia was the brand name of a PDA manufactured by Casio. It used Windows CE as the Operating system. Casio was one of the first manufacturers of PDAs, developing at the beginning small pocket-sized computers with keyboards and grayscale displays and subsequently moving to smaller units in response to customer demand.

It was quickly discovered that most consumers wanted smaller devices, so the Palm-size PCs were developed. Japanese models of these units differ in both model number as well as appearance. The E-5x and/or E-5xx models are Japanese versions, colored blue instead of silver. The following versions were developed; A21-S for Student, A22-T for Teachers, A-23G for German with AZERTY keyboard, A-20F for French.

Casio always advertised the fact that their devices could be updated. Casio decided it would not issue an update for the E-100 and E-105, and a lot of owners of the devices complained. Because of the complaints, Casio offered to update the devices to the newest version of the Operating system if the owners sent in the device and paid a fee. Since the operating system was stored in ROM and not flash memory, the only way to upgrade was by replacing the ROM.
