Well I have one but don't use it for feedback. It's in a box
somewhere. I got it and wrote a little vb program for it
but that's about it. Might be a cheap way to add encoder
input for a handwheel though. Not sure how many folks
are using feedback with steppers or step driven servos.
Not many probably.

Over my head, I'll let Ray field that one
