EXPANSION SLOTS
On single board expansion cards, the 3.85 mm diameter
located in the upper right- hand corner is not required, thus
providing a small extra area of board space. The two 3.85
mm holes on the left-hand side of the board together with
the connector fixing hole in the lower right-hand corner can
then be used as tooling holes, if required.
