The HW1's read the LCD memory constantly (DMA)...
that of course uses up bus bandwidth... on HW2's, the lcd memory is mirrored,
and because of that, there is no need to snoop for the lcd mem so the bus is
freed up for other tasks.

I do know that the HW1 uses 70ns SRAM
while the HW2 uses 85ns SRAM.
