memory. The OZ-8200 was launched at the same time with 128K of internal non-volatile memory. Both models shared the same form factor. A custom fitted leather, padded carrying case was also available for both models. The devices opened in landscape rather than portrait orientation with the IC Cards slot position changed accordingly. The OZ-9600 and OZ-9600II were the last of in this family of PDA in the Wizard line. Later Wizard organizers were smaller, dispensing with the expansion slot and soon bore little resemblance to the original OZ-7000. In 1991 Sharp released also a series of IC cards allowing programming in BASIC for the OZ-7000, thus turning the organizer to more a PDA-like device. The same version of BASIC had been used in later Sharp PDAs, both Wizards and pocket computers such as the Sharp PC-E500S. The line of devices utilizing touch-controlled IC cards had been concluded with the IQ-8500 model. Starting with the OZ-8900 and, later, the OZ-9xxx series, Sharp moved to production of clam-shell design/touch-sensitive display devices. Newer Wizards had an integrated IR transmitter allowing data exchange with PCs or other OZ-9xxx devices. The innovative design had the main features of the initial Zaurus line which continued this PDA family for Sharp. Due to new features, IC Cards for these devices were not backwards compatible with the OZ-7xxx series. The later Sharp Wizards were something between an electronic databank and a PDA. They were small, lightweight devices with keyboards but no touch screen, running on a Zilog Z80. Starting with the ZQ-770, model numbers had the prefixes either of OZ (for the USA market, where the prefix from the beginning was meant to be a pun on The Wizard of Oz) or ZQ (rest of the world) followed by a number, for instance ZQ-770, a non-US organizer with 3 MB memory, thus abandoning the IQ prefix used earlier.
