From the project

iMac G3 IVAD board initialization with an arduino

These are the KiCAD project files for this project.

-imacg3333mhzslotloadingJ20adapter_board This board is the "brains" of the operation, it sends the init sequence to the IVAD board and also sends EDID information to any device that requests it when conencted to the VGA port.

-imacg3downconverterboard_adapter This board takes 24VAC from the analog board via the the J22 board and converts it to standard computer power supply voltages. +12VDC, +5VDC and +3.3VDC. This board also has a footprint to include a connector to connect a CPU fan.
