Kontron / PEP VM30 Single Board Computer

The Kontron/PEP VM30 is a 3U VMEbus single board computer built around the 40 MHz MC68EC030 processor with integrated 40 MHz MC68882 floating-point coprocessor and 20 MHz MC68302 microprocessor. Designed for safety-critical and industrial applications in harsh environments, the VM30 delivers real-time processing capability in nuclear power stations, seismic installations, and automation systems. It pairs with real-time operating systems like OS-9 and supports multi-tasking architectures with Modula-2 software routines.
