Fidelity Electronics 6502 dynamic CPU clock divider

|

TODO:
|
||||
- improve clock divider? it seems a little bit slower than the real machine.
|
||||
Currently, a dummy timer workaround is needed, or it's much worse (doing it with
|
||||
a synchronize() will make it even worse).
|
||||
Is the problem here due to timing of CPU addressbus changes? We can only 'sense'
|
||||
the addressbus at read or write accesses.
