Add RGB output to your Sega Master System Mark 2 and unlock superior picture quality and upscaler compatibility on the diminutive little console! No longer will the Mark 2 SMS be limited to RF output! With this upgrade we will install a full RGB upgrade including bypass amp which will make sure that any jail-bar effect is as minimal as possible. Output will be by a 9 pin DIN connector compatible with Sega Megadrive 2 RGB cables. For the widest compatibility with cables, sync is output on two pins:-

75ohm Csync on pin 4 – Required for SCART cables designed for composite video for sync, HD Retrovison or other RGB to component cables.

TTL Csync on pin 5 – Required for SCART cables wired for composite sync, such as “Packapunch” cables.

Note that composite video output is not available with this upgrade. Attenuated composite sync (Csync) is provided on pin 4 and is compatible with most hardware, including HD Retrovision cables and RAD2X.

This upgrade is for the Mark 2 Sega Master System only, as pictured below. If you have a Mark 1 Master System and need a jail bar fix for it, please contact us.
