The Dragon 32 Sound Extension Module is a cartridge by J.C.B. (Microsystems), that contains a General Instruments AY-3-8910 sound chip (Also found on Amstrad CPC, Spectrum 128, +2 and +3, MSX, Atari ST and other machines).
This allows the Dragon to play interesting sound effects and complex chiptunes without taking all processor time.
The cartridge also adds two 8-bit I/O ports (provided also by the AY-3-8910).
The sound chip can be operated via the new commands in BASIC provided in the cartridge ROM, or via the 0xFEFE and 0xFEFF addresses.
It was sold for £34.95.
