TEA1002

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

The chip is capable of displaying 40 × 24 text blocks with 8 × 8 pixel characters, corresponding a theoretical resolution of 320 × 192 pixels (within borders), with the character set allowing for a 80 × 72 semigraphics display. Correction update - this chip does not generate the display itself, its only a colour encoder.

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