Ah, you engineers DO Think Different ...!

Sort of a sliding switch, right? Preferably with some sort of
indicator when the proper setting is reached, so the novice user won't
have it on the wrong setting.
A more complex (and of course, costly) version would be able to tell
which Newton device was connected, and self-adjust.
So perhaps in this instance, cheaper is better!
