Proper IC positioning is indicated by a dot or square marking located on
one end of the device. A corresponding mark will be silk-screened on
the PC board and printed on the kit's parts-placement diagram. To

below. Pin numbers always start at the keyed end of the case and
progress counter-clockwise around the device, as shown:
