KanjiTalk was the name given by Apple to its Japanese language localization of the classic Mac OS.
[1] Early versions of KanjiTalk were based on a proprietary Kanji script input system called 2.0 and 2.1.
[2] Developments following version 2.0 laid the groundwork for what eventually became Kotoeri, introduced with System 7.1.
[3] KanjiTalk 1.0 debuted in 1986, alongside Apple's universal System 3.0, and first distributed with the Mac Plus.
[4] Apple had intended to ship its new PowerBook models with System 7, but development of the new OS was taking longer than anticipated, so Apple released a special version of System 6.0.7.1, with support for KanjiTalk, in order to market its new laptops in Japan.
