2732 EPROMs in various manufacturers refurbished that have been machine cleaned and legs straightened, and programmer verified blanked and erased so they are completely ready to program. Widely used in 1980s arcade game boards and pinball machines to store game code, graphics, and sound.
The 2732 EPROM is one of the most iconic memory chips of the early-to-mid 1980s. It was the standard memory choice during the "Golden Age" of arcade games and the birth of solid-state pinball.
Because many original factory ROMs (like the 9316 and 9332) are now obsolete, the 2732 serves as the primary modern replacement chip for dozens of machines.
In arcade cabinets, the 2732 was heavily utilized by industry giants like Atari, Namco/Midway, and Nintendo to store core CPU code, vector graphics, and primitive audio data.
In pinball, the 2732 is legendary for its role in early solid-state MPU (Main Processor Unit) and speech boards. It is most frequently found in machines built between 1979 and 1985.
Original Bally and Stern machines used custom factory mask ROMs (9316/9332) that frequently die. Operators universally jumper-modify the MPU boards to use two 2732 chips at locations U2 and U6 to keep these classics running:
Williams used 2732 EPROMs for CPU game code and speech modules.
