Nice pong built by a german student for electronics in 1978. With the help of a fellow student who built the boards for this pong he boughts parts for another 12 speciments and built all of them by hand with his own soldering iron. All is built around the classic GI AY-8500 chip and is housed inside a nice plastic casing. 11 of theses nice systems were given to his friends as gifts in the end of the 70ties. The one he kept now belongs to my collection :-)
