Sharp Wizard

The Sharp Wizard is a series of electronic organizers released by Sharp Corporation. The first model was the OZ-7000 released in 1989, making it one of the first electronic organizers to be sold.

The OZ-7000 was about 6.1 inches (155 mm) tall, 3.5 inches (90 mm) wide closed, 7.25 inches (184 mm) open, and 0.75 inches (19 mm) thick closed, making it much larger than current PDAs. It featured a connection port to attach to a Windows PC or Macintosh, an optional thermal printer and cassette tape backup, 32 kilobytes of memory, an 8 by 16 character black and white LCD, and an expansion slot for accessory cards.

The functionality of the OZ-7000 included a memo pad, a telephone pad, calendar and scheduling with alarms and repeating events, multi-time zone clocks, and a calculator. All the basics found in PDAs since. The keyboard was not QWERTY, although later models changed the orientation of the screen and keyboard to allow that.

The expansion cards were about the same size and shape of PC Cards but predated that standard and were incompatible. The slot was behind touch sensitive plastic allowing for up to twenty "buttons" on the card. The original selection of cards included memory expansion cards, a thesaurus dictionary, and some games.
