Note orientation of PC connector

A
3 wire connector cable is needed to connect the BASIC Stamp 1 to
a PC's parallel port. A male DB25 is wired up as shown to a three
female pin connector. Solder three wires to the 3 pin connector,
then to the DB25 as shown above.
Plug
the DB25 into the PC parallel port one and the three pin connector
into the circuit board. Align the 3 pin connector's edge labelled
"PC edge" above (the Gnd wire) with the "PC"
label on the circuit board.
The
PC label indicates the Gnd connection, which is the pin with the
square copper pad; the other two pins have round pads.
