No, it is only 2 to the 9th power - that's 512. Us old-time machine
language computer programmers know obscure stuff like that.

Have you tried calling Acu-Rite? I think they are supposed to be helpful
with old models. You might be able to get a maintenance manual,
or at least the info needed to do setup.

I have a Mitutoyo that came with the lathe that I'm rebuilding, and
you can switch between radius and diameter from the front panel.
I think it is a cryptically labeled 1/2 switch.
