cybernesto 118279b8e7 Corrected frequency values based on the real CPU Clock frequency 
The Mockingboard PSGs base their frequency on the Apple II Clock.

Based on this discussion I made a spreadsheet to calculate the correct values of the frequency tables and updated the ones used by the Music Construction Set player.

Music Construction Set Mockingboard interrupt player for Apple II

This is the source code included in the first Music Construction Set version with Mockingboard support. The original version could not be assembled because it was missing some important elements.

A working version was included in the Mockingboard Developer's Toolkit which included some additional corrections but was not available in source form.
