OMG - just found this epic thread and had to check out all nine pages, truly awesome, cannot give you enough kudos, I am blown away. Sorry to revive an old thread, but I love this game - when I was 8, I snuck out to the arcade whenever I could and even in 1980, the Killer Shark game was still going strong at my local Alladin's Castle. I remember loving that game, even though I was young enough, the shark's bloody death (and fear of them after Jaws anyway). I couldn't even play it unless I could find one of the step stools the arcade kept lying around for younger players. I never forgot that game - and now, I'm amazed at how it works, and how cool it looks.
@pacman - I actually just happen to be writing up a documentary video on the early shark arcade games. do you mind if I use this thread as a resource for my video? While your videos are short, they show some great shots that show how it works - that's actually how I found this thread; I was looking for info on projection based games like Killer Shark. I'd happily credit you and provide links to your YouTube or website. And, this may be too big an ask - but I see you're in San Diego - any interest in showing your restoration off? I'm also in SD, if you'd be willing to let me see it and/or play it, that would be really cool for the video. If not, no worries - thank you so much for sharing all of this!
