SGI Indy 13w3 question

The "Hardware Developers Handbook" from sgi has pages of detailed information
on the pinouts of sgi's 13W3 "Monitor Output" - followed by several pages of
timing information. Many of the none coax pins are system dependent.

Here's sgi's official statement on their 13W3:

Coax signals:
A1 - Red
A2 - Green
A3 - Blue
Other signals:
1 - See Table
2 - Monitor type 0
3 - See Table
4 - See Table
5 - See Table
6 - Monitor type 1
7 - Monitor type 2
8 - Ground
9 - Ground
10 - Ground

This is followed by several pages of detail, but here's the drift:

Onyx

1 - Monitor type 3
3 - NC
4 - Stereo Sync
5 - Stereo power +10V

Onyx2

1 - SCL (Serial Clock)
2 - Serial Data
3 - NC
4 - Horizonal sync
5 - Vertical sync
6 - DDC (+5V)
7 - DDC Ground

Indigo, Indigo2, Indy

3 - Composite sync (dependent on video board)
4 - Horizonal sync (dependent on video board)
5 - Vertical sync (dependet on video board)

In total there are 32 pages on video interfaces alone in the manual!

That's why I've found its a lot easier to use sgi's own monitors with sgi
systems. I have used other monitors - IIyama, etc., but none of them are
inexpensive...
