Sun Adapter != IBM Adapter != SGI Adapter
That's weird because my Sun adapter definitely works on my Indy. question of what
sync types your monitor supports.
Suns use different pins for sync than SGIs (and Suns usually use
composite sync, while SGI use separate H and V), and SGIs also use some
pins for monitor type sensing. However, quite a lot of Suns and most
SGIs also provide sync-on-green, so if the monitor supports that, and
the other signals don't cause confusion, it should work.
Contrary to popular belief, most SGIs from the Indigo onwards do not
require a SOG monitor.
Sorry, I don't know what the pinouts are for HPs or IBMs (apart from
R,G, and B). If anyone cares to tell me, I'll add the info to my crib
sheet:
13W3-SGI
================
pin A1 - Red/R-Gnd
pin A2 - Green/G-Gnd
pin A3 - Blue/B-Gnd
pin 1 - monitor type 3 (ground this on old machines, leave open on
Indy etc)
pin 2 - monitor type 0 (LSB)
pin 3 - Composite Sync
pin 4 - H Drive
pin 5 - V Drive
pin 6 - monitor type 1
pin 7 - monitor type 2 (MSB)
pin 8 - digital gnd
pin 9 - digital gnd
pin 10 - digital gnd or Sync 2

pin 4 - sense ret
pin 5 - Composite Sync
pin 6 - n/c
pin 7 - n/c

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...
