Interfaces
• VMEbus compliant, occupies two 6U slots
• Two 16550-compatible serial ports
• PS/2-style keyboard and mouse port
– Key Features
• Pentium processor architecture for integer and floating-point workloads
• Integrated dual-port DRAM accessible from VMEbus
• Onboard Ethernet and SCSI controllers eliminate external dependencies
• Graphics adapter with dedicated video memory
• Flexible DRAM configuration supports parity and non-parity modules
– Operating System Support
Windows NT OS, VxWorks, and LynxOS compatibility.
– Compatibility & Integration
Full VMEbus compliance enables integration into existing 6U backplane architectures. Dual-ported DRAM provides direct memory access from VMEbus, reducing system latency for inter-module communication. PCI-based SCSI and Ethernet controllers support standard Linux and embedded drivers.
