Prototypes

DEM3000H - Shipped to developers in 2011, 0.945 is its minfw.

 There are no major changes in terms of specification (functionality) between DEM-3000H
 and the older DEM-3000G. 
 In terms of the hardware, however, the following differences exist:
   - The performance of the GPU has been enhanced (approximately 10% to 20% - also
      dependent on the shader program)
   - The Bus error generated because of a hardware bug has been fixed.
