add Map RAM emulation
The emulator is now capable of booting up to the point where the BootPROM accesses the floppy and hard drive controllers.
Still TODO:
Lots of I/O registers
Memory mapping, banking and protection
Supervisor R/W restrictions (only SV mode code should be able to R/W I/O regs, user RAM is fair game)
