add Map RAM emulation

  • by Philip Pemberton <philpem@philpem.me.uk> [Wed, 01 Dec 2010 22:43:52 +0000] rev 27
  • 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)
