The scale indicates approximately the proper distance travelled, but
only counts in one direction. In other words, move forward 1 inch and
the readout will indicate approximately 1.0000; move back to the
original position and instead of returning to 0.0000 it reads, more or
less, 2.0000.

I'm reading this with a bit of interest. My bridgeport has what I believe are
magnescales. They look old. Blue cold cathode display, some what dim, two joysticks for
zeroing, setting presets. Reads out to 0.0001" which is overkill on a mill.

Does this sound like your scales? Just curious, can't remember what model but I found
squat about it on the web and I'm pretty good at finding things. Not as good as Iggy,
that man is a wizzard from some of the stuff he has drug up.

Part of me wants it to die so I can buy a DRO with features, the other part of me is work
with it, more money in the toy budget.
