View source for 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.

The S/SC internally doubles the E clock provided on the CoCo's expansion port, and has problems when operated at the CoCo 3's high speed without modification.


== Third Party Software ==

SoundMaster 2.0 by Jim McDowell is an OS-9 Level II program for the CoCo 3 with 512K of RAM.  It is a BASIC09 program that provides a graphical interface for designing sounds to be played on the S/SC.  It includes device drivers and descriptors for accessing the S/SC at both slow (unmodified) and fast (modified) speeds.

== Games ==

The following games are known to produce sound effects and/or speech with the S/SC if present.  Offsite links are to L. Curtis Boyle's list of [http://nitros9.lcurtisboyle.com/coco_game_list.html Tandy (TRS-80) Color Computer Games]:
