[Coco] Instruction cycles per 60Hz frame.

[James Ross]

continued:  actually the math can simplified to ...

cycles_per_60hz_frame = (1d / 60d) * 1000000 * coco_clk;  // 0.8948... MHz
double_cycles_per_60hz_frame = (1d / 60d) * 1000000 * double_speed; // 1.789... MHz

which gives the same results:
standard 60hz (vsync) frame = 14914.7727272727 cycles per frame
double speed 60hz (vsync) frame = 29829.5454545455 cycles per frame

so, unless I am really confused (which is quite possible!), then the #'s above have to be correct ... ok moving on then :) :)
