Thanks
to those who helped me obtain a "digitizing sight" for an HP 9872 (or 722X or
747X) plotter. This is a device which takes the place of a plotter pen and allows
accurately positioning the pen over a point on a drawing in order to capture the
coordinates. The 1980 HP Measurement/Computation catalog lists this on page 657 as
accessory part 09872-60066.
