ABSTRACT:
A cursor for use with an X-Y grid tablet comprises a single integral transparent plastic member having a substantially flat face with a circular groove machined or molded therein and crosshairs etched into the area enclosed by the groove. The member is mounted on a rotatable plate and magnet wire is wound inside the channel by using a needle having an eye large enough to allow the wire to pass therethrough. The base is rotated the exact number of times to establish the desired characteristic of the coil. A removable cap which fits over the area within the channel may be used to hold the wire while the base is turning. The ends of the wire pass through an aperture to the opposite side of the base. The completed coil is potted within the channel using an electrical grade epoxy.
