The Abaco Systems / VMIC VMIVME-7740-870 is a 6U VMEbus single-board computer engineered for real-time embedded applications requiring high-performance processing and integrated I/O. Built around an Intel Pentium III processor with MMX technology operating up to 1.26 GHz, the module delivers 32-bit addressing with 64-bit data bus architecture and 256 KB on-die Level 2 cache. It functions as both VMEbus controller and slave, supporting A32/A24/D32/D16/D08(EO)/MBLT64/BLT32 transfer modes across VMEbus Rev. C.1 specification.
