If you want to ask questions about how the machine works, peculiar details, the differences between models, here it is !
How to program the oric hardware (VIA, FDC, ...) is also welcome.

no, no.. its interesting :)

The AY Clock is derived from the CPU clock of 1Mhz.
This is unlike the Atari ST which runs its YM(Functionally compatible) at 2Mhz, the Spectrum at 1.77Mhz, the Amstrad at 1Mhz i think.

Incidentally the difference in clock speed means retuning of the pitches must be administered to songs converted across. This can cause problems if the Hardware envelope is used in songs because of the low resolution at higher frequencies in bistable modes.

But i suspect you intended to ask about how the clock is divided down to provide the resolutions for Pitch and Envelope curcuits?
