STICdigitizer (for Intellivision) - c0pperdragon/LumaCode GitHub Wiki

This board can be installed into a vintage Intellivision game console to create a lumacode representation of the display. This lumacode signal can be processed with a compatible upscaler to deliver a pixel-perfext HDMI display.

Theory of operation

The circuitry is quite simple as all video information is available in digital form, so all that is needed is to serialize the 5-bit color+sync information to lumacode which can be done with a flip-flop, a multiplexer and some logic gates.

Installation details

Solder the mod board to the underside of the mainboard, just under the STIC chip. Use the "1" marking to get the orientation correct. Bring out the lumacode signal with some wire and maybe install a permanent RCA socket to the case.

To avoid using the RF signal altogether, consider installing an A/V mod. Please refer to other sources on how to do this, as this goes beyond the scope of this documentation.

There is a great video from Mark showing how to do this installation.

RGBtoHDMI software

The RGBtoHDMI software does not yet provide a profile and palette data for this machine. After installing the normal release, you can add the files from this ZIP to the SDcard to have a working profile: intellivision_extra_files.zip
