Hey Swinksy great post   

Im sure those vids where from pin fest   The games where together and off all the time    I think thats Mitch and me playing them as the owner turned them on for us

David Hankin told us that they pinched the B/G idea  from Space invaders    We had a good laugh   

Back in the eighties  Orbit leasure center Parramatta   had all these games all brand new      Those whwre the days      Howzat

All the Orbit  leisure centres were owned by the Hankins and is also where they got the name for their first machine Orbit1.
