- How many times do we have to say this: The CHIP RAM in the A3000 is
- 16-bit from the custom chip side. Gary does some magic to make the
- A3000 CPU see it as 32-bit wide memory. This does *not* mean that
- any of the hardware on the custom chip side of things is 32-bit. Infact,
- it is not; it is 16-bit.
