I can't remember exactly which one was first but I reckon it was either Gorgar,Kiss,Playboy,Flash Gordon,Centaur,Six Million Dollar Man or Evel Knievel. We used to feed some coins into those, usually at Orbit 1 in Newcastle ( owned by the Hankin Brothers I believe ) or at the Top Takeaway on the highway at Belmont.
Those were the days.
Funny I can never remember playing an 'em' when I was a kid, but now I own three & love 'em!
I used to put heaps of coins into the new Space Invaders as well.
Lookin' back I don't know why ,when I could of been playing Pinball instead.
