Tetris for Sharp Electronic Notebook (1989)

In December 1989, Sharp released a version of Tetris for its Denshi Techō electronic notebooks, which were marketed as Bware in Japan and Wizard or IQ in other regions. These devices, which won a G-mark Good Design Award in 1988, were notable for their ability to run software from IC cards, including around 30 games. Tetris was part of a gaming boom during Japan's economic bubble era, which spurred innovation in consumer electronics. The Tetris version for Sharp's devices was significant as it was one of the earliest handheld adaptations of the game, following the Game Boy's release earlier that year. The game features a unique interface, allowing users to switch between gaming and organizer functions, although switching back to the game resets it. The programming was likely done by BPS (Bullet-Proof Software), and the game includes non-standard scoring and leveling mechanics. The Tetris game for Sharp's electronic notebooks is less documented compared to other versions, highlighting a gap in historical records about these devices and their software.
