The A24 Base Address of the 3000-46 can be derived from the value stored
in the Offset Register (06h). To obtain the A24 base address, take the 8
most significant bits of the Offset register and map them to the 8 most
significant bits of the A24 Base Address. All other bits in the A24 Base
Address are set to zeroes.
