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. There is no ROM-based program in the S/SC (except the ROM for the onboard microcontroller), but the 54 page manual contains complete programming information and many example Color BASIC programs demonstrating the capabilities of the interface.
