As is, the original NEC PC Engine SuperGrafx, also known as just the SuperGrafx, outputs only composite video. This mod will upgrade the console to output RGB.

A comprehensive install includes the following:

• Replace the 5 pin DIN with an 8 pin DIN to support the extra RGB pins
• Install RGB amp designed for NEC consoles
• remove the centre plastic post from the shell that is known to puncture a hole in the main PCB
• replace 2 ceramic capacitors on the board to remove jailbars in video output

NOTE(S):

• A SuperGrafx system must be provided in good working condition
• RGB amp and 8 pin DIN port are provided as part of this install
