I got the 13W3 pinout from the port of my Image-I. It IS correct.

Missing Pins

The key position pin-9, above, corresponds with an obstruction on many system unit video ports, this is intended to reduce the likelihood of something other than a monitor being plugged into the port and so offers limited protection to the electronics on the video adapter card.
DDC uses this pin for power and reassigns the ID bits for DDC signaling.

Older monitors do not use all the pin positions available.
The following were manufactured with pins intentionally missing:

Note that 6091I-19i and 9504 use the Image Plus 13W3 connector, which is self-keying by virtue of its three coaxial connectors, it is always fully pinned.

HDD15 to 5BNC

From a cable that Dick Evans gave me, along with a 6091-019, here it is:

All shields are tied together to shield on HDD15 and pins 4,6,7,8,10,11

Pins 5, 12 and 15 are NC.

Waiting for SOMEONE to send me the pinout of a WORKING Image-I to 5BNC cable, used on a 6091-xxx monitor.

OK, the 150M is PCI, BUT it uses the same cable as the GXT150. 09G3589, FC 4229. It's about 1.83m long.

There is a Display Conversion Cable, 13W3 to 5 BNC, 52G3255 FC4213. It's about a foot long.


Matrox 13W3 to 5BNC Pinout

NOTE: Pin numbering and arrangement images the GXT150M pinout:
   HSYNC uses Pin 5, but the return is Pin 10.
   VSYNC uses Pin 2, return on 10.

If you look at the GXT150M pinout:
   HSYNC is Pin 5 with return on Pin 4.
   VSYNC is Pin 9 with return on Pin 10.
