In terms of hardware, bits are packaged in sets in the
form of bytes and bytes usually are built in multiples of 8
bits. You _could_ manufacture 12-bit hardware devices,
but it would be much more expensive than the 16-bit
devices you can buy off the shelf. The design of the
digital hardware for the 836XL was almost certainly 16-bit -
- the software designers simply chose to use only 12 of
the 16 bits available. Your new driver uses them all.
