• Fix mallocing issue with ram array
  
  RAM storage array was not being correctly allocated at startup. This caused memory access issues... Spotted with Valgrind, fixed.

add Map RAM emulation

• Wed, 01 Dec 2010 22:43:52 +0000
• 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)
