2024-03-02: The wiki ran out of disk space, so things were not working. This has been resolved by adding another 5GB of quota ;-) Thanks to Tim Lindner for reporting the issues.
2020-05-17: If a page gives you an error about some revision not being found, just EDIT the page and the old page should appear in the editor. If it does, just SAVE that and the page should be restored. OS-9 Al (talk) 12:22, 17 May 2020 (CDT)
Speech/Sound Cartridge (26-3144A)
The Speech/Sound Cartridge allows a Color Computer to produce monaural synthesized music, sound effects, and speech. It includes a PIC 7040 microcontroller that feeds data from the CoCo into an AY3-8913 Programmable Sound Generator and an SPO256-AL2 Speech Processor. It can produce speech from text and music in 3 voices. The sound is played on the Color Computer's monitor or TV through the SND pin on the CoCo's expansion port. The S/SC has a 2K RAM for storing sound effects or speech.
