The Monitor Master is a monitor switcher intended for use with the Goldengate Bridgeboards such as the Goldengate 486 SLC. The device connects to both the bridgeboard's ISA graphics card, the Amiga's graphics card (or scandoubler) and automatically switches the monitor between signals when the bridgeboard becomes active. The device has both 9pin and 15pin connectors so it supports both the old EGA monitors , and (S)VGA monitors.
