Nearest that I can remember, byte size varies by machine. It is NOT an
eight byte quantity. This is probably the motivation to use _octet_
instead of bytes in formal descriptions.
An example of byte sizes: CDC 1604 6 bits
CDC 6000 12 bits
PC 8 bits
UNIVAC 1100 7, 8, 9, 12 bits
PDP-10 7 bits (and others?)
