AY

Get your brand new ZX Spectrum hardware at: The current version of the AVR AY does not have I, O, but only takes care of the sound part. So for a replacement on a computer mainboard that uses the I, O ports, an original AY38912x replacement chip is required. But for Harlequin kits and other sound devices, it s a perfect choice. You might notice a slightly offtune sound comparing the AVR AY to the AY38912, which will be fixed in the final version that ByteDelight will be producing. It s caused by the clock frequency on this AVR AY, which is 1. 75MHz for Pentagon machines the ZX Spectrum version will be 1. 77MHz.
