Yep definitely one disc on Tron . I remember from when I had mine stripped down to a bare playfield for a clean .


Be interesting to see how that whole disc/head set-up works on Kiss .

I surprised to see that it achieves the affect that it does.  But I'd say that Borg would be using the same thing on KISS.  It makes sense in the location they have the disk on KISS.  Given I've had so little plays on Tron due to its lack of availability here, I'm looking forward to experience that mechanism a lot more on KISS that will be on location everywhere.
