A pair of embedded miniature television sets was discovered deep within the circuitry of a Siemens 191A21 integrated circuit that we assume is configured for operation video components (perhaps the picture-in-picture feature). The Siemens Semiconductor Group is now Infineon Technologies, poised to command a large market share of the industry.

The integrated circuit was donated to the Silicon Zoo by German photographer Karl E. Deckart, who is one of our featured microscopists. To view more of Karl's work, visit his Mikro/Makro website, which contains a sampler of his transmitted and reflected light images captured with a microscope.
