Richard:

It would be DIFFERENT... But "better" would depend on the intended
application.  If, for example, the application required that the
generator never return the same value twice in a row, taking 8 bits
out of a longer shift-register WOULDN'T be better.

Also, the original question asked for code that used as few registers
as possible.  An "8 out of 24" solution would require at least 3 or 4
times as many registers as the one-register 8-bit solution.
