For my Atari 2600, if I set the jp1 jumper to open on the 26000RGB mod board, this sets the sync to TTL and not 75 ohms. If I use TTL for the Atari 2600 6 switch model, what resistor value would I need in the sync line of the SCART RGB cable?
I have a SNES TTL where I use a 330 ohm resistor in the CSYNC line in that multiout RGB SCART cable. Is the SNES and Atari TTL Voltages the same?
