I'd say that video- equals to GND. I'd combine H and V sync and try it
on a composite monitor.

Subject: CRT monitor for SUN 3/140
I have been through 3 CRT monitors that died ( circa
1989) that were
attached to a SUN 3/140 station. The monitors are SUN Model M19P114 part
no 365-1051-01.
The pin out on the 3/140 is
1-VIDEO+
2-GND
3-HSYNC
4-VSYNC
5-NC
6-VIDEO-
7 GND
8-GND
9-GND
VIDEO+ and VIDEO- are ECL levels , and HSYNC and VSYNC are TTL levels.
I believe it is EGA monochrome. I am not sure if this SUN has non standard
( proprietary) output for video. Is there anyone that knows a way to
connect this SUN to a standard LCD VGA monitor using some kind of video
converter or by using a multi-sync monitor ?
