AY-3-8912A-TS Turbo Sound upgrade

The AY-3-8912A-TS is a fully functional replacement (pin compatible – providing both programmable sound generator and IO) for the increasingly difficult to source AY-3-8912A sound chip as well as supporting an additional 3 channels of tone + noise (Turbo Sound).

Features include:

• 6 channels of tone + 2 noise channels (Turbo Sound compatible)
• Bidirectional 8-bit input/output port
• Pin compatible with the AY-3-8912
• Support for clock frequencies from 1MHz to 2MHz
• Designed for the Sinclair Spectrum(128K/+2/2A/2B/+3)
• Output levels closely match the AY-3-8912
• Frequency response equivalent to the AY-3-8912

The AY-3-8912A-TS is simply installed as a replacement for the existing AY-3-8912 and is compatible with software designed for a single AY-3-8912A as well as programs that provide Turbo Sound audio.

Note:   the AY-3-8912A-TS is not compatible with the CPC range Amstrad computers.

Installation will require the removal of the existing AY-3-8912 (a socket for the replacement is recommended).
