Emerson / Motorola / Force Computers CPU-30BE/16 SYS68K Single Board Computer

The CPU-30BE/16 is a VMEbus-based single-board computer built on the Motorola MC68030 processor running at 25 MHz with integrated MC68882 floating-point coprocessor and memory management unit. It delivers 32-bit processing power for embedded systems, real-time control, and data acquisition in industrial environments, combining on-chip instruction and data caches with comprehensive I/O connectivity and firmware support.
