Switch settings: Facit 4070 tape punch

[Dennis Boone]

 > The older Facit 4070s (including all the ones I've every worked on) have

Tony and others interested:

A photo of the component side of the board, and one of the back end of
the unit, are available at:

These images are quite large, about 5 MB each.  Forgive the quality;
setting up some kind of copy stand and lights for this kind of work is
still on the "pending round-tuit" list.  But you should be able to read
the chips, etc.

Meant to do this a week ago, but it's been one of those weeks.
