The Abaco Systems VMIVME-7700-011 / VMIVME-7700-011000 is a VMEbus Single Board Computer engineered for deployment in rugged, mission-critical environments. Built around an Intel Ultra Low Voltage Celeron processor, this passively cooled single-slot Eurocard delivers reliable performance without active thermal management. The board functions as a system controller or peripheral CPU in multi-CPU VMEbus architectures, with transparent PCI-to-VMEbus bridging and full VME64 compliance.
