Abaco Systems / Radstone PPC4-750-1000B High-Performance Single Board Computer

The Abaco Systems / Radstone PPC4-750-1000B is a 6U VME64 single-board computer engineered for high-reliability embedded applications in defense and aerospace. Built on the PowerPC 750 architecture with PReP compliance, it delivers sustained memory throughput via a dedicated processor-memory bus and supports five ruggedization levels - from air-cooled to conduction-cooled configurations. The platform combines onboard SDRAM, FLASH, ferroelectric nonvolatile RAM, and dual PMC expansion slots, enabling rapid technology insertion while maintaining full I/O compatibility with earlier PPC4 generations.
