Alpha-Numeric

When Solid State electronics made mechanical Score Reels obsolete in the late 1970s, the first generation of digital displays were simple Seven-Segment LEDs — capable of showing numbers and a handful of blocky letters, glowing amber or red against the darkened backbox. By the early 1980s, manufacturers had moved to Sixteen-Segment displays that could render the full alphabet with reasonable clarity. For the first time, a pinball machine could speak.

Bally and Williams used alphanumeric displays extensively throughout the 1980s and into 1991, when Plasma displays took over. Machines could now show player names, shout encouragement — GREAT SHOT, SUPER BONUS — and display the high-score initials that motivated players to put in one more quarter. Speech synthesis chips arrived around the same time, and the combination of spoken words and readable text gave machines a personality that score reels never could.

The characteristic amber glow of a Sixteen-Segment display became the visual signature of an entire era: High Speed, Earthshaker, Cyclone, Taxi, Bride of Pinbot. The displays were capable of simple animations — scrolling text, flashing patterns — and designers used every available trick to suggest life within those glowing segments. When Williams introduced the first Plasma display in 1991, the alphanumeric era ended almost immediately, but those segmented readouts remain instantly recognizable to anyone who spent time in an arcade during the 1980s.
