Currently, a dummy timer workaround is needed, or it's much worse.
Is the problem here is due to timing of CPU addressbus changes? We can only 'sense'
the addressbus at read or write accesses.
- EAG missing bankswitch? where is the 2nd half of the 32KB ROM used, if at all?
- granits gives error beeps at start, need to press clear to play
- finish fphantom emulation
- PC has 14KB RAM. 0000-0fff and 8000-9fff is certain, where does the remaining map to?
