@DamageX:
If you just swap the clock-source the E clock will be double as fast when communicating with the 8520 CIAs, which makes the diskdrive step double as fast, creating problems with trackloaders and if I remember correctly, when you use a terminal-program, the baud rate you select will actually be doubled.
Here is a description of a more proper 14MHz 68000-accelerator which gives correct timings.
These accelerators doesnt increase the bus-bandwidth in any way. The reason that the 68000 benefits from a higher clock is that the 68000 generally spends more time executing functions internally, than it spends reading/writing memory, so there is an noticeable increase in total performance if the time spend executing functions internally is decreased by increasing the clock.
