General sound 512 emulation

[chernandezba]

Hi

I’m planning to add General Sound emulation to my ZEsarUX emulator

I have found information about programming the GS: type and format of the messages, ports etc

But I have not found info about how internally works the GS:
-ports used (the same as on the speccy side?)
-controlling dac interface: ports, volumes etc
-interrupts: how the interrupts are fired?
Etc...

Anyone has that info? I don’t know Russian but using a translator should be enough (I hope )

Regards
César
