Test tone app modifications?

[Steev]

The app tests Osc 1 but is it possible to modify this to test other Oscs? I had a look at the ReadMe files and didn't see this. The MOS 6581 pinout indicates that Pin 8 is "CS with a line over it". It wasn't clear to me whether all Oscs are on this pin or whether they are on separate pins. Pinout is here if it's of interest. Thanks for any tips.

Neither. The CS pin is just the "chip select" pin, that enables/disables data IO to the SID. It doesn't enable disable any part of the SID in particular. See: http://en.wikipedia.org/wiki/Chip_Select

Long story short: That pin doesn't have anything to do with what you want to do.
