6809E 8-Bit Microprocessor (40-Pin CPU) The 6809E is a powerful 8-bit microprocessor commonly used in classic arcade PCBs during the early and mid-1980s. This processor served as the main CPU for many arcade boards, executing game code, handling player inputs, and coordinating communication between memory, sound hardware, and video circuitry. Known for its advanced architecture compared to earlier processors, the 6809E provided improved instruction sets and efficient memory addressing, making it a popular choice for more complex arcade games. A properly functioning CPU is essential for reliable board operation, making the 6809E a common replacement component during arcade PCB repair and restoration. Key Features Motorola 6809E 8-bit microprocessor Standard 40-pin DIP (Dual In-line Package) Used as the main CPU in many classic arcade boards Handles game logic, timing, and hardware communication Ideal for arcade PCB repair and restoration work Used In Arcade Games Such As Circus Charlie Juno First Track & Field Hyper Sports Star Wars Qix …and many other classic arcade titles Some arcade boards use the 6809E processor in conjunction with other supporting chips or adapters. In certain Konami systems, the 6809E can be used with a 42-pin Konami-1 adapter, which is included with some HighScoreSaves kits. Installation Notes Installs into a standard 40-pin DIP socket on compatible arcade PCBs Ensure proper notch orientation when installing the CPU Recommended for technicians performing arcade board troubleshooting or restoration *Can be used with a 42-pin Konami-1 adapter (included with some HighScoreSaves kits). *Manufacturer brands may vary.

8080 8-Bit Microprocessor (40-Pin CPU) The Intel 8080 is a classic 8-bit microprocessor that powered many early arcade machines. Introduced in the mid-1970s, the 8080 became one of the foundational CPUs used in the first generation of dedicated arcade hardware. On arcade PCBs, the 8080 serves as the main processor responsible for executing the game program, handling player inputs, controlling game timing, and coordinating communication with video and sound hardware. Because it manages core gameplay functions, a properly functioning CPU is essential for reliable arcade board operation. The processor uses a standard 40-pin DIP (Dual In-line Package) and installs into a compatible socket on the arcade PCB. During arcade board troubleshooting or restoration, the 8080 is sometimes replaced to resolve boot failures, game resets, or non-functioning boards. Key Features Intel 8080 8-bit microprocessor Standard 40-pin DIP package Main CPU used in early arcade hardware Handles game logic, timing, and system control Suitable for arcade PCB repair and restoration Used In Arcade Games Such As Space Invaders Space Invaders Deluxe …and other early arcade titles using 8080-based hardware Installation Notes Installs into a standard 40-pin DIP socket on compatible arcade PCBs Ensure correct notch orientation when installing Recommended for technicians performing arcade PCB troubleshooting or restoration *Manufacturer brands or markings may vary.

8035 8-Bit Microcontroller (Sound CPU, 40-Pin DIP) The 8035 is an 8-bit microcontroller from the Intel MCS-48 family that was commonly used as the sound CPU on classic arcade PCBs. This processor manages audio control, timing signals, and communication with the sound hardware that generates music and sound effects during gameplay. In many arcade boards, the 8035 operates alongside the main game processor and is dedicated to handling audio-related tasks. By separating sound processing from the main CPU, arcade hardware was able to deliver more complex sound effects and music while maintaining smooth gameplay performance. The chip uses a standard 40-pin DIP (Dual In-line Package) and installs into a compatible socket on the arcade PCB. Because the sound CPU is critical for proper audio operation, the 8035 is often replaced during troubleshooting and restoration of classic arcade boards. Key Features 8035 8-bit microcontroller from the Intel MCS-48 family Commonly used as the sound CPU on arcade PCBs Standard 40-pin DIP package Handles audio control, timing, and sound hardware communication Ideal for arcade PCB repair and restoration Used In Arcade Games Such As Donkey Kong Donkey Kong Jr. Donkey Kong 3 …and other classic Nintendo arcade titles Installation Notes Installs into a standard 40-pin DIP socket on compatible arcade PCBs Ensure the notch orientation matches the socket when installing Recommended for technicians performing arcade PCB troubleshooting or repair *Brand or manufacturer markings may vary (for example NEC 8035 or compatible equivalents).
