The ZON X-81 is a sound generator based on the famous AY-3-8912 PSG.
This is a remake for my ZX-81+35 clone. It features stereo sound outputs, and also enables the GPIO's, to which an SD-card slot is connected, which hopefully Will enable, with help of some software expansion in ROM, to read SD-cards. Adittionally the board serves (can serve) as an interface to a classical edge connector, or to another ZX81+35 expansion board (with pinheader connector).
I started by investigating the original ZON X-81, and soon found out there were two verslons, the original ZON X-81 and the later, "Spectrum compatible" ZON X.
