The B12 provides 12 sideways ROM sockets. It can be used on its own
or plugged into the B20 or B32.
 
The B20 has 20K of usable memory, as a selectable shadow screen.
 
The B32 has 32K of usable memory selectable as:
  2 x 16K sideways RAM
  1 x 16K sideways RAM + 16K shadow RAM
  1 x 12K sideways RAM + 20K shadow RAM
