On Spectrum-based machines, the AY chip is normally clocked at half the CPU clock. Melodik, the [[Timex 2000 series|TC2068]] and the Pentagon have an AY clocked at 1.75 MHz. The [[Timex 2000 series|TS2068]]'s AY chip is clocked at 1.764 MHz. The Timex machines use different ports to the 128. | On Spectrum-based machines, the AY chip is normally clocked at half the CPU clock.
