This is something of a "Work in Progress" checkpoint of several features
that are all half baked:
1. Allow loading of 16KB ROM files at address $C000 at run-time, not
just at startup. See the "Load ROM..." File menu item.
2. Introduces the notion of "CPU Behaviors", so the core 6502 CPU
implementation can match the behavior of either an early NMOS 6502, late
NMOS 6502, or CMOS 65C02. Very little of this is actually implemented so
far.
3. Adds a completely bogus implementation of the 6522 VIA (it
does absolutely nothing right now).
4. Changes the address of the ACIA in the simulated system to match a
real hardware implementation I put together.
