Can anyone confirm whether a Mac IIsi spits out sync-on-green (and only
sync-on-green) or not? I've found mixed info on the 'net so far.
I've got a system here which makes encouraging startup noises, but isn't
outputting any video to a VGA screen (adapter cable OK with my other Macs).
If it's SoG-only, well, there's my problem :-) If it does output h/vsync
like my other Macs then I need to look elsewhere (most likely nonsense
NVRAM settings, I expect).
cheers
