The Abaco Systems VMIVME-7698-132 is a VME/VME64 single-board computer engineered for industrial embedded systems requiring real-time performance and multi-OS flexibility. Built around an Intel Celeron processor with MMX™ technology running at up to 366 MHz, this board delivers 32-bit addressing with a 64-bit data bus architecture and includes 128 KB on-chip L2 cache. The system supports up to 256 MB of SDRAM via a single 144-pin SODIMM, with dual-port access to the VMEbus for high-throughput data transfers.
