Tiki-100 was released under the original name 'Kontiki-100' in the spring of 1984. Thor Heyerdahl threatened to open a legal case on the use of the Kontiki name, with reference to the name of his famous raft. The name was changed to "Tiki-100" as a result. Around the same time, Computerworld magazine claimed the operating system "KP/M" was a direct copy of CP/M, due to KP/M being able to run CP/M software. As a response to these claims, KP/M was renamed "Tiko" to avoid direct association to CP/M and Digital Research.
