Sound and Speech Interfaces

The ZX80, ZX81 and TS 1000 computers lacked sound synthesizers, a moderately common feature of other home computers.

Sinclair owners could expand their computer with aftermarket sound synthesizers (most based on the General Instruments AY-3-8910), speech synthesizers and speech recognition systems.

Amplifier unit allows complete control over speech volume. Works with 9V battery included.
TS 1000 TS 2068
