The 6 pin connector has the following pinout according to my copy of
the docs:
1 - GND
2 - Video (output)
3 - -5V
4 - +12V
5 - key (n/c)
6 - Light Pen (input)
My clone card only has a 3 pin header connected to pins 1,2 & 3. Pin 5
should be missing on the card and blocked on the pluf to prevent
incorrect connection.
