Gene

Based on what John has done, his 6809 is running at 12.5 MHz with a single phased 
clock. I am not sure if his core runs single clock for each intructionor not. Even at  
two clock cycle per instruction would yield an effective 6025 MHz. By synthesizing 
the the CPU core alone, static timing indicates that a single instruction may operate 
up to about 19 MHz.
