Brilliant game, I love Orbitor 1, it takes a very different type of pinball playing skill to be able to master it.

Still looking for a shaft and scoring disc for the spinning bumper, but it's all working, just one is not scoring.

Simon at amusement worx in Adelaide might have some parts for the spinning bumper.
I know approx 3 years ago he replaced some on a machine with 2 NOS ones that he had, he may still have the old parts that might be useable. Given there's not many of these games floating around he may actually still have the old bumper parts.
