This was Fujitsu's first notebook style personal Japanese language word processor. It was announced in October 1989, and had the following features:
- Lightweight (2kg) compact body, the size of an A4 binder
- Large liquid crystal screen capable of displaying 40 characters x 21 lines
- A modem card could be built-in, so the system could be used as a communication terminal when out of the office.
- Equipped with a 3.5-inch floppy disk drive. Compatibility with the OASYS Series.
- High-quality printing was achieved using a special-purpose 48x48 dot thermal transfer printer (sold separately)
In October 1990, Fujitsu added an enhanced model, the OASYS 30AD-EX, equipped with a transmissive liquid crystal with backlight (the backlight could be switched on/off with a single touch).
