I’m also interested in any answers from New York owners and/or players. I happened to purchase a Spirit of 76 with an add-a-ball hack and would like to understand how close it comes to the NY machine. As currently configured, my S76 awards (via the extra ball feature) a ball when the replay score is achieved. Achieving more than one replay score with the same ball still only awards the one extra ball. Specials still knock and add a replay, as do matches (once I made additional changes).
IPDB states that the NY machines they saw contained the replay unit. Did all New York’s have the replay unit and they just painted over the window on the backglass? Do they match? What is the Special? It was a commemorative pin and didn't have to meet the old New York anti-gambling laws so I assume Gottlieb had some flexibility.
I have played the New York machine at Silverball Museum but wasn’t interested in these issues at the time. I will probably head back there soon with a little more purpose.
