INVICTA GAMES ELECTRONIC MASTER MIND - 1979.
This game works when it feels like it probably due to some corrosion in the battery compartment, but I'm sure it could be cleaned up by someone who knows what they are doing.
It has its original box, which has some signs of ware.
Also included are the original instruction leaflet, score cards, and warrantee card.
Please see photographs.
Please contact me should you require any further information.
Battery NOT included.
