I found this today and bought it (surprised?). It was $5, completely intact, at a Flea Market. The shrink wrap was opened at one end of the manual (by someone else) - otherwise perfect condition! Made in Israel. Guessing 70ish or early 80s.
Update: Just found one here on ebay (maybe only a tiny bit in better condition) for a Buy Now price of $99!
Question - Play with it or not?
