Abaco Systems / VMIC VMIVME-7695-455 Single-Slot Pentium II Embedded SBC

The Abaco Systems / VMIC VMIVME-7695-455 is a single-slot VMEbus embedded Single Board Computer built around an Intel Pentium II processor running at 333 MHz with MMX technology. This compact SBC integrates 32-bit addressing with a 64-bit data bus, delivering superscalar performance of three instructions per clock cycle alongside dynamic branch prediction and 512 Kbyte L2 cache. Designed for demanding industrial control, simulation, data acquisition, and automated test environments, It has dual-ported DRAM access to the VMEbus while maintaining a passive heat sink design for reliable operation without active cooling.
