Back then some friends and I got hold of some lovely 20" Sun monitors that were sync-on-green only but none of our cards supported it.
No matter! A transistor, a couple of diodes, and half a dozen or so resistors soldered into a DE15 plug shell made the "sync plunger" that cured all your woes.
I probably still have a couple lying around. I could still just about draw the circuit from memory, not much good in these HDMI days.
- a96 1mo agoMy memory says Sun used composite sync in the 13W3. I do remember making some cable mods as well to use monitors across Sun, Sgi, and a few other machines. Some used H+V, some C, some SOG. Maybe thankfully I no longer remember which ones were which after all.
