Marble Queen

The Marble Queen pinball machine appears to be one of the last electro-mechanical pinball machines produced during the twilight years of the EM era, just before the industry's transition to solid-state electronics. The name 'Marble Queen' suggests a regal, fantasy-themed machine that likely featured elegant artwork and classical motifs common in late 1970s pinball design.

Typical of the era, the machine would have featured mechanical score reels, relay-based logic systems, and the distinctive clicking and chiming sounds that characterized EM pinball machines. The gameplay likely focused on traditional pinball elements such as drop targets, pop bumpers, and spinning targets, as these were standard features in late-EM era machines.

As one of the final machines from the electro-mechanical period, Marble Queen represents an important transition point in pinball history, coming just before the revolutionary solid-state electronics that would transform the industry. While specific production numbers are not well documented, machines from this era typically saw production runs between 2,000 and 4,000 units.

The historical significance of Marble Queen lies in its placement at the end of an era, as manufacturers were preparing to embrace the electronic revolution that would bring digital displays and solid-state control systems to pinball machines. These late-EM machines are particularly valued by collectors as they represent the peak of mechanical pinball engineering before the digital age.
