📦 Ordering Information
The correct identification is:
XYCOM XVME-674 VMEbus PC/AT Processor Module
Available technical references identify XVME-674 as a VMEbus processor board with 80486 CPU architecture, not a general VME I/O module.
When replacing an existing unit, confirm processor speed, memory size, firmware/software environment, and VME chassis requirements before installation.
*Power consumption, weight, and environmental values are reference values and should be verified against the exact hardware revision before engineering use.
