Overview
The Jr. Pac-Man (Speedup Hack) arcade machine refers to a highly popular, aftermarket hardware modification for the original 1983 Bally Midway arcade circuit boards. This modification, driven by a "Speed-Up Chip," multiplied the main character's traversing speed up to four times faster than standard factory settings without altering the speed of the ghosts or overclocking the main hardware clock. Originally designed by third-party groups like Two-Bit Score in the late 1980s, these hacks were widely installed by arcade operators across North America to dramatically increase difficulty, shorten player sessions, and ultimately drive up quarter intake.
