What Is the 84-W8404F01A?
The 84-W8404F01A is not a standalone model name. It is a Motorola (now Emerson) factory PCB/Assembly Part Number that maps directly to the MVME2400 series of 6U VME single-board computers. When you see this number on a label or in a BOM, it refers to a configured MVME2400 board—typically the MVME2400-011 standard configuration.
If your system documentation lists 84-W8404F01A, you are looking for a PowerPC-based VME processor module designed for embedded industrial control, data acquisition, and legacy system support.

Why the MVME2400 Series Matters
The MVME2400 was designed as a flexible, long-lifecycle embedded controller for industrial and telecom applications. Its key architectural advantages include:
Dual PMC Expansion: Two IEEE P1386.1-compliant PMC slots allow custom I/O expansion without replacing the base board, reducing long-term cost of ownership.
VME64 Extension Connector: 5-row 160-pin DIN connectors provide additional I/O while remaining 100% backward compatible with legacy VME systems.
PowerPlus II Architecture: An optimized processor/memory subsystem with a 100 MHz local bus and SDRAM support for deterministic performance in real-time applications.
These boards were widely deployed in industrial automation, semiconductor equipment, telecommunications, and defense systems where VMEbus infrastructure was already established.
