I think the modules A-160/161 have the disadvantage, that they don't
start with step 1, but with step 2 (and 160 also does not count
musically - should be a down counter). So I would not invest into those.
I think a new generation of PIC based counters and dividers would be
great. Perhaps even a module group that also would be able to provide /
read an internal adress bus, so one might combine it with the A-154.
