[Coco] XRoar Accuracy (was: Introduction)

[Arthur Flexser]

I can confirm that the number of CPU cycles in a VSYNC interval is
slightly different on the CoCo 3 from the earlier CoCos.  I recall
having to change a timing constant in a CoCo 1/2 program I sold years
ago for that reason when the CoCo 3 came out.
