Re: Single tones on the Mockingboard?

The mockingboard sample disk has some SFX routines that can be easily modified for this -- I spent some effort trying to write an IRQ-based playback routine but fell short of getting the darn thing to work correctly!

Tom Charlesworth actually pulled off a great conversion of a Speccy chiptune to playback on the mockingboard.  (Cybernoid)

Anyway, I remember one thing that kicked my butt: If you don't init the card properly, it will basically do nothing with you data.  I think it's more of a 6522 thing than it is an AY thing though, if my hazy memory is working at all.
