What is it?

System Alpha is a direct replacement combo CPU/Driver PCB for Williams System 3-7 pinball machines (1977-1984). It removes common failure points and improves long-term reliability.

What's in the box?

1x System Alpha main PCB. Optional: System 7 Add-on PCB kit for selected System 7 games.

Installation

Plug-and-play replacement: no rewiring or soldering required for standard install. Load ROM files by USB, then install and run setup from coin door service switches.

Warranty

1-year non-transferable warranty covering manufacturing defects. If compatibility or setup issues occur, contact support before return.

Product Overview

his board is a 100% hardware-faithful reproduction of the original Pong “E” revision arcade mainboard.

It is designed for:

Restoring or repairing original Pong arcade cabinets

Building a standalone Pong arcade system using the optional Arcade Power & I/O Module + Rotary Controllers

This is not an emulator, not FPGA, and not microcontroller-based logic.

It is a full TTL hardware state-machine implementation, just like the original 1972 design.

What’s Included

1 × Pong “E” Revision Mainboard (fully assembled and tested)

Optional:

Arcade Power & I/O Module

Rotary paddle controllers (analog potentiometer type)

Technical Specifications

Video Output: NTSC CVBS (Composite Video)

Audio Output: Analog audio

Power Input: 8V – 15V DC

Game Logic: 100% TTL discrete logic implementation

CPU: None (original hardware architecture)

How It Works

The original Pong is a pure hardware state machine.

There is:

No CPU

No firmware

No software rendering

Every aspect of gameplay is generated directly by hardware:

Ball X/Y position registers

Paddle input sampling

Collision detection and angle logic

Score counting

Sound generation

Horizontal & vertical scan timing

Composite sync signal generation

The video signal is generated directly in hardware and outputs analog composite video compatible with standard NTSC displays.

Paddle control uses analog potentiometers. The voltage is converted directly into paddle position via hardware comparison circuits.

This board preserves that original architecture.

About Pong (1972)

Pong (1972) was the first commercially successful arcade video game developed at Atari.

It was designed by engineer Allan Alcorn under the direction of company founder Nolan Bushnell.

Originally assigned as a “training project,” it became a global arcade sensation.

The prototype was tested at Andy Capp’s Tavern in Sunnyvale, California. The coin box famously filled beyond capacity within days — proving the commercial viability of video arcade games.

Technically, Pong was revolutionary because:

It used TTL logic instead of software

It generated composite video directly from hardware timing circuits

It implemented gameplay entirely through digital state machines

It required no processor

Pong directly launched:

The arcade video game industry

The home console market (Home Pong, 1975)

The widespread adoption of LSI chips in gaming hardware

Atari’s later platforms, including the Atari 2600

From a historical perspective, Pong represents one of the foundational origins of the modern video game industry.

Use Cases

Arcade restoration projects

Educational demonstration of discrete digital logic design

Retro hardware research

Museum or collector display systems

DIY arcade builds

Important Notes

This product is an independent hardware reproduction.

It is not affiliated with, endorsed by, or sponsored by Atari.

Requires external power supply (8–15V DC).

Requires composite display (NTSC).

Why This Board Matters

Modern recreations often use:

Microcontrollers

FPGA

Software emulation

This board does not.

It recreates the original logic structure using discrete TTL — preserving timing behavior, signal characteristics, and hardware interaction exactly as intended in the early 1970s.

For collectors, engineers, and historians, this is not just a game board.

It is a piece of digital logic history.
