While HP and Compaq competed for the premium market, Casio’s Cassiopeia line made Windows CE accessible to price-conscious buyers. From pioneering Palm-size PCs to value-oriented PocketPCs, Casio earned a devoted following.
Early Windows CE Pioneer
Casio was among the first Windows CE licensees:
Cassiopeia A-10 (1996)
One of the original Handheld PCs:
| Spec | Value |
|---|---|
| Processor | MIPS 75 MHz |
| Display | 480×240 mono |
| RAM | 2 MB |
| OS | Windows CE 1.0 |
These clamshell devices predated PocketPC by four years.
Palm-size PC Era
Cassiopeia E-10/E-15
Casio’s Palm-size PC entries competed with early Palm devices:
- Monochrome display: Power efficient
- Compact design: Truly pocketable
- Windows CE 2.0: Basic but functional
- Affordable pricing: Mass-market target
Cassiopeia E-100 Series
The E-100 brought color to Palm-size PCs:
| Model | Display | Innovation |
|---|---|---|
| E-100 | Color TFT | First color PSPC |
| E-105 | Color TFT | Improved battery |
| E-115 | Color TFT | Built-in voice recorder |
These devices launched at Pocket PC 2000 alongside iPAQ and Jornada.
PocketPC Generation

| Display | 240×320 TFT | 240×320 TFT |
