Overview
The VMIC VMIVME-4120 (part number 332-004120) is a VMEbus-compatible printed circuit board engineered for industrial control and automation applications. Originally developed by General Electric and later supported by Abaco Systems, this board integrates seamlessly into standard VME chassis and systems. The unit is fully functional and tested, making it a cost-effective replacement for industrial automation facilities.
