Here's a beast of a manual that I've scanned and posted. Will send
the original for the cost of shipping (assume at least 5lbs of paper
here, coming from 60070.)

Looks like numerical control for machining, not strictly a "computer"
but certainly an early programmable device. 1970 edition but the
earliest date on it is 1962. Can deliver to VCFMW.
