Description
Description
Add-on module to provide SVIDEO Output for Atari 7800 SECAM console.
This card replaces original sVideo to RGB circuit that is sub-optimal and directly outputs sVideo signal over the same connector
Original SCART cable stays compatible.
It requires you monitor to support sVideo over SCART if you want to keep the original cable, otherwise a new cable can be made with standard sVideo connector.
