I was 99.9% sure that's what I would find, but JUST in case, I thought
I'd ask.

Thanks, I'll look.

What I've made up are some PCBs, with a quadrature reading PIC mounted
to the back and a small 16x1 line LCD display on the front.

It makes a single channel DRO, small enough to be mounted by the
handwheel.

I guess it would be easy enough to recode for SPC-in.

Thanks again.
