The Kontron/Rotec Technology Gamma7 is an industrial VMEbus-PC that bridges VME architecture with PC compatibility for mission-critical control and data acquisition systems. It combines a 500 MHz Intel Mobile Pentium III processor with VME master/slave/controller capability, delivering high reliability in demanding operational environments where system uptime and data integrity are essential. The system supports configurable SDRAM from 32 MB to 256 MB, IDE storage up to 20 GB, and dual display output (LCD and CRT) with resolution support to 1600 × 1200 pixels and 16.7 million colors.
