T.T Mahjong

T.T Mahjong (T.T マージャン, lit. Tī-Tī Mājan), is a mahjong arcade game that was released by Taito Corporation in 1981 only in Japan; it utilizes two Zilog Z80 microprocessors (running up at 2.5 MHz), with a General Instrument AY-3-8910 running at 1.25 MHz for sound. The game's name is displayed in Katakana on its title screen, with 1 purei 1 koin (1プレイ1コイン) and 2 purei 2 koin (2プレイ2コイン) below it - and the Kanji text Azumaya (東家) is displayed to the left of the player's current score, with the Katakana text Dora (ドラ) displayed to the left of a currently-selected tile. Texts including Sutehai seyo (ステハイせよ), and Tsumo mataha pon hi ichi seyo (ツモ又はポン・干一せよ) are also displayed above the player's rack of tiles; the game's control panel also comprises a record-breaking nineteen buttons (Kan, Reach, Ron, Chi, Pon, and A-N), setting the standards of many later mahjong games.
