??? how the heck ST can have 5 or 6 bitplanes? Or in other words - what do you need to do to have 5 or bitplanes on ST - how many CPU cycles?
Classic case - mouse pointer - how many CPU cycles are used on ST to simply simulate HW sprite? Everyone calculate CPU cycles but we can't ignore OS overhead or typical functionality required by GUI.
