I like mysteries. As I collect more and more pinball machines I find mysteries for which I have found no answers. Do you have any pinball mysteries of your own? If you do, please post them here!
My Mysteries:
1. Steve Kordek, while working at Williams, invented the drop target in 1962 for Vagabond. Williams used the drop target, but only one at a time. Gottlieb took the drop target idea and expanded on it with banks of drop targets. Without a doubt, Gottlieb can be thought of as the drop target king and many of their 70s games used them even though Williams was the first to use the modern drop targets that we are so familiar with. The Mystery - Why did Williams allow Gottlieb to have a monopoly on the popular and lucrative pinball feature drop target banks until the late 70s??
2. Many of the Project Pins I find are missing the backbox back door. I understand that back doors can be separated from their machines. The Mystery - Where all of these back doors?? Were they used to keep oil from dripping on garage floors? Is there a room somewhere in the universe where some alien has hoarded a gazillion pinball machine back doors?
3. I often find the coin boxes in the Project Pins I buy. However, the coin box top is usually missing. The Mystery - What happened to all of them? Why would they be removed in the first place?
4. The Mystery - Why didn't Williams label their early SS boards - IC, capacitor, connectors, etc.?
5. IPDB: "Triple Action was the first game to feature just two flippers at the bottom of the playfield. Unlike in modern machines, the flippers faced outwards. These flippers were made more powerful by the addition of a DC (direct current) power supply. These innovations were some of many by designer Steve Kordek." #Triple Action, Genco 1948.
The Mystery - Why did early EMs use DC powered flippers and later games, especially in the 70s, did not have DC powered flippers even when DC powered slingshots and pop bumpers were standard?
