On the 80 wire connectors,
the following pins measured as common: 2, 19, 22, 24, 26, 30, and
40 (Motherboard, Gray and Black).
On the connector that connects to
the Motherboard pin # 34 does not connect to the ribbon cable but
is connected to common. Some cables have a hole in the cable as a
way of disconnecting pin # 34 from the other two connectors.
On the middle (Gray) connector pin
#28 is not connected to the ribbon cable. (C/S Slave).
The extra 40 wires, one of which
is inserted between each data wire, are all connected in common
and are connected with 2, 19, 22 etc. on each connector.
On most IDE connectors on
Hard drives and CD-ROM Drives, Pin 20
is missing.
