This may or may not be the correct section because this is sort of a hack (adding some connectors) but it is mainly about a 68030 mac connector.
I would like to attach a VGA (as well as a sound) connector to the monitor via the card edge connector on the analog board. One problem, I can't fin the full pinout ANYWHERE.
Does anyone have a pinout for this connector? It is a 40 pin connector, so it's not that easy to trace (even with a multimeter).
From what I understand the monitor is an average VGA monitor that uses a 640x480 resolution and it has 2 sound amplifiers for stereo I would guess.
Any help is very much appreciated,
(Also I know about dangerous voltages on the analog board. I let it discharge and it is out of the computer)
NEWS: Unfortunatly I have decided to abandon the project of using the original analog board. Leck of information and the difficulty has made me decide to use a generic CRT monitor board instead. Thanks for all your help but with my current skillset I cannot finish this project.
EDIT: Is there any way to change the horizontal scan voltage to make the horizontal frequency from 66.67Hz to 60Hz for my project to work properly.
EDITEDIT: Will attaching pin 7 to +5 volts make the power supply come on without the motherboard?
