This object has a two row 50-pin connector on one side that is connected by solder traces to 50 holes. A network of other traces connect the pins of a 16-pin dual inline IC pads to the pins of one or more other IC pads, as well as holes for mounting passive components. The 5 pads on this object have IC sockets and 4 of the sockets are populated by 7130 IC packages. Thin pink wires connect the traces from the connector to holes provided near the sockets. Diodes and resistors are soldered in other holes. The board has been roughly hewn just along the row of sockets, and one lead of most of the passive components have been lifted off pads that used to be on the missing part.
