Tiny 'handheld' Pong system for Siemens Bildmeister TVs. It is unknown if the pictured console is only a pair of controllers that could be plugged in a TV system that had it´s Pong system built in or if it could be played with any other TV Set with Din plug. There existed some similar systems from labels like Grundig, Blaupunkt or Sennheiser. They were all designed for the use with TV sets of their own brand and are mostly not compatible with other TVs.
