Summary of operation:

The soundcard is designed to fit into a standard 16 bit ISA bus slot on a desktop P.C. Up to four cards can be fitted in the one system, giving 32 channels total. A custom power amplifier was designed to power speakers placed remotely from the computer. Filtered switch inputs recieve TTL level trigger information for each channel.

The boards have been used in Mini Golf courses in Australia to provide sound effects when the player sinks a ball into a hole. A playlist of sound effects adds considerably to the overall effect for venues which have a 'theme' to them.
