Thought I'd show this late 1960s GM parts control card that somehow managed to survive on an unboxed and odd shape NOS part I recently bought. Haven't seen one of these punch cards in years - probably high tech and state of the art back in the day. I do recall seeing these in the late 70s and early 80s, but I think the format was a little different. This appears to be a 2/68 version.
