Good plan. It's convenient to use the A160 with the A150 VC Switch for
16-step A155 sequences. You can also tap off two or more of the
divided A160 outputs to vary the sequence with some logic processing.
(I don't have the A166 logic module unfortunately, but it isn't
difficult to accomplish the same things with an A138a, A132, and
A165).
