I960

IGT i960 Platform
Introduction
The IGT i960 Platform is one of the most recognizable generations of gaming hardware developed by International Game Technology (IGT). Introduced during the late 1990s and early 2000s, the platform powered a wide range of video slot machines and formed the foundation for numerous successful game titles deployed in casinos worldwide.
Built around the Intel i960 RISC processor, the platform combined reliable industrial hardware with a modular architecture that simplified maintenance and field service. Over its lifetime, the i960 platform evolved through several hardware revisions while maintaining a high degree of compatibility between components.
Architecture
A typical i960-based gaming machine consists of several major subsystems:
Main CPU board
Video controller
Game storage media
Security hardware
Input/Output controller
Bill validator and peripheral interfaces
Touchscreen or button panel
Display system
Depending on the cabinet configuration and software revision, hardware layouts may vary, although the overall architecture remains consistent.
Software
Games are typically stored on removable media and protected through multiple security mechanisms. Depending on the software generation, machines may use hardware security devices, signature verification, or platform-specific authentication methods.
System software includes diagnostics, hardware configuration, accounting functions, communication protocols, and game execution.
Serviceability
One reason the i960 platform remained popular for many years is its relatively service-friendly design. Many components are modular and can be replaced individually, making repairs practical for trained technicians.
Common maintenance tasks include:
Power supply replacement
CPU board replacement
CMOS battery service
Display troubleshooting
Storage media replacement
Peripheral diagnostics
