Need help getting a Pachinko machine running

[bluefish44]

Hi all and thanks in advance for any help. I recently acquired two machines (a Sankyo pachinko and a Aladdin Master Pachislo). Both look to be in pristine condition but When I plug either of them in, nothing happens. The Pachinko needs power to operate I believe, won't work on gravity alone (I'm guessing it's a early 80's model?). I think both of the machines came over directly from Japan. Could there be an issue with Japanese power voltage versus US? I don't know a thing about electricity. Anyway, I'll post a pic of both machines (attached) and an help would be greatly appreciated! -Jason
