OK, Wes.  You've got me curious.  "So how does it keep from scanning
continuously when there's no selections?" is the question that comes
to mind, of course. :-)

I believe the physical changer mech was either identical or nearly so
to my F-120, right?

My first guess is you've adapted the seeburg style "set a counter to
two when a selection is made, subtract one when you change scanning
direction (or maybe each scanning pass?), keep the mech powered until
you've counted back down to zero" approach to this mechanism.  There's
not a nice, pre-existing switch contact to hook onto for the "subtract
one when you change direction" part of that solution, though.  Perhaps
an intrerupted optical beam...

So...  How?  :-)
