No.05847 Ace Tester Mar 9, 2010, 00:34	Clocking the M68000 to 10MHz? Don't you mean clocking the Z80 to 10MHz? The Z80 is Salamander's sound CPU. When overclocked to 10MHz, the speed of the music is perfect, however, some notes in the music appear to come out wrong when the Z80 is overclocked that high. Why is that?
