The Apple IIGS VGA Adapter connects your IIGS to a VGA monitor that supports 15kHz.
It takes the composite sync signal from Pin 3 of the Apple IIGS RGB port and sends it to the appropriate pin on the VGA connector. No more jumpers needed on the motherboard!
It also includes a sync separator for monitors that require a vertical sync signal.
* Note: For VGA monitors that do not support 15 kHz, you will still need a frequency upscaler, in addition to this adapter.
