The upper Clock Input of the module A-149-1 belongs to both the "n+1" and "2
power n" outputs. I think the correct alternative term is "and" because both
outputs are affected by the clock input, i.e. "a new random voltage is
generated at the N+1 and 2N output".

So far nobody was asking. Otherwise we would have revised this explanation.

And Peter Forrest is rehabilitated ! He did not proofread the A-149-1
manual.
