The TEA1002 is a PAL video encoder chip[1] produced by Mullard in 1982 and used on the Mattel Aquarius computer, the AlphaTantel Prestel adapter and the Microvector 256 color graphics display interface for Nascom and Gemini computers.[2][3][4][5][6] It was also used on teletext decoders and color bar generators associated with video test equipment.[7][8]

It generates 16 colors based on Luminance, Chrominance and Saturation, usually with the 8 basic colors being similar to the EBU 75% color bars.[9]
