Btw, please excuse my lack of knowledge on EMs but isn't there another Sinbad that isn't "Eye of the Tiger"?  

Yes there is. Sinbad is the Solid State version of Eye of the Tiger. I'm not sure on numbers of either but not many Eye of the Tigers were built but by comparison there were plenty of Sinbad's.
Fantastic game by the way. Very simple rules but beware it will chew you up and spit you out very quickly. Defiantly amongst my top favorites. I haven't played Eye of the Tiger though but I'd imagine it to be just as good.
