Yeah EB,
Not working as described, I dont have a schematic for it but as I said have not tried too hard to get it going as I would not want to have the ball running around in its present state, black rubber crud everywhere. A few of the toasted coils have broken plastic formers, I guess they probably still operate but dont inspire confidence.
I might try to give it a basic clean and follow DD's links to getting it fired up first. Have a lot going on at present so cannot devote the time I would like. Will chip away at it. When I did power it up it appeared the big stepper motor in bottom of cabinet was energised but not moving (buzzing away), when it did move it seemed to be struggling.
The coils that have been toasted are BX, O, R, H, Q, U, L, M.
Cheers
Dave
