Video hardware

The upper WORD is used the coarse classification. This can be:

 -1 =    Non-ST-compatible hardware; in this case all hardware 
         accesses must be avoided
  0 =    Atari ST (260 ST, 520 ST, 1040 ST, Mega ST, ...)
  1 =    Atari STE (1040 STE, Mega STE, ST Book)
  2 =    Atari TT
  3 =    Atari Falcon030
  4 =    Milan

The lower WORD is reserved for finer differences.
