The ZOE Interface was developed by xAD^Nightfall and Damiano “Manosoft” Colombari.

The Zoe interface lets you connect the PAL Mattel Intellivision console to a TV/ monitor through the RGB signal of a SCART connector, dramatically increasing the quality of the video signal and bringing it to the highest possible quality: the original output is a modest RF/Antenna signal.

The interface is connected in place of the National LM1886 IC (TV Video Matrix DAC) to take the RGB and Sync signals and convert them for the SCART output.

This interface is not compatible with the NTSC (USA) Mattel Intellivision console because the NTSC version doesn’t use the LM1886 IC: the original video signal is never converted from RGB to Composite and then to RF (Antenna).

The assembled kit is available and you can buy it now from ebay (An installation service on the console will be available for less experienced users)
