• 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)
