Does it handle Sync on Green? I found out the hard way that the IIci's built-in video is SoG ONLY, which was a big surprise to me. Fortunately, I had one LCD that handled SoG, but it's fairly uncommon these days. The wire-only adaptors (even the excellent Griffin MacPnP) don't convert SoG because it generally requires active conversion and thus has to be powered.
Hmmm not sure. But I didn't know that the IIci internal only did that. I can ask a friend to bring over something compatible. I used to do a lot with SGI and Sun systems/monitors and a lot of them were funky fixed resolutions at different frequencies and often SoG. It was pretty maddening honestly. Thanks for the heads up on that. I wouldn't be surprised if my 15" Hansol brand LCD can do SoG, it's an oddball and I've thrown 24khz "EGA" arcade video into it and other stuff and it usually works. I *think* the machine isn't thinking because all the data pins on the PROMs are dead on power on. I just see no activity. I got schematics and found the reset circuit loops through the audio chips or something. I see that signal is high until I hit the reset button then it does go low. Was looking for a power on reset circuit that might not be letting the CPU run? That is my "next check." - Ethan
