The 4-player EM version of this game is Gottlieb's 1978 'Sinbad'. The 2-player EM version is Gottlieb's 1978 'Eye Of The Tiger'. Pictures here are portions of a Sample game (serial number 01290 S) having its start button and flipper buttons made of red plastic, just like the game shown in the manufacturer's flyer. It appears that production games use green plastic for these buttons. Also, the sample card holder, while using black and orange colors unique to Sinbad, shows the words "INSERT COIN ONLY WHEN COIN ENTRANCE IS LIT" which are not found on later cardholders for this game. Sinbad was the first of the System 1 games to use this apron having the style of art shown on it. This game was also made with the lower cabinet using metal for the entire front, entire back, and entire bottom. The sides of the cabinet were made of wood, as was the backbox. The pedestal upon which the backbox connects to the cabinet was made of metal. The serial number is stamped in the wood on the inside of the cabinet near the shooter rod. We asked Wayne Neyens about the metal cabinet. He comments:I think that it was Doc's idea but I forget. It had many draw backs, as I recall it was very noisy, hard to assemble and needed more room than we had available to do the assembly.Wayne refers to Roman F. "Doc" Garbark, head of mechanical engineering at Gottlieb. We previously showed a date for this game of May 1978 and a production run quantity of 12,950 units. The new date and quantity are per Gottlieb documentation. Quantity produced - domestic: 5,758 Quantity produced - export: 6,242 Total quantity produced: 12,000 The flyer indicates that this game was a direct tie-in to the 1977 Hollywood movie "Sinbad and the Eye of the Tiger". Sinbad (Sindbad) the Sailor was a character in one of the folk tales of classic Arabic literature known collectively as The Thousand and One Nights (aka The Arabian Nights).
