Hey Phil, it’s John here. Frans Pilger was nice enough to do a series of continuity tests on his Miami Beach’s score disc to confirm connections between the score disc, mixer #2 and the spotting disc. He discovered several errors in the spotting disc diagram on your web site. My Miami Beach has a number of operator modifications to the score disc wiring, so Frans’ results are more believable than my earlier data. The following images show the corrections in green. The upshot is that four lugs on the spotting disc should have their labeling changed. Both our games have a jumper between lug #20 and #21 on the spotting disc. Frans states that his jumper looks factory original. Mine, on the other hand, looks like a homemade addition (see lower image for the wire looping around the corner by the spotting disc label). The #20 lug is wired to only a few rivets, so adding a jumper from #21 to #20 would make the game slightly more liberal. (Would Bally really provide such an “expansion” capability for operators worried that their game was too tight? Beats me.)
A couple more points: The 54-6 lug on the score disc top row between 10-5 and 60-2 is a documentation error on Bally’s part. That lug is not connected to any rivet on the score disc, and there is no wire connecting to the lug. The real 54-6 is next to the red dot labeled “8” on the score disc diagram. Also, the score disc 43-3 wire does not appear in the schematic. Frans said he’ll take another crack at figuring out what 43-3 connects to after he finishes a few ongoing projects in his shop.
Let me know if this is as clear as mud and I’ll try to make it better.
