Motorola MVME104 | OEM Embedded Control Replacement

Description

1. Motorola MVME104 | OEM Embedded Control Replacement

Unboxing & Physical Snapshot

• Model & Brand: Motorola MVME104 VMEbus Single Board Computer (SBC). This module belongs to the early Motorola MVME10x family and uses an MC68010 10 MHz processor with 512 KB shared DRAM. The MVME104 version includes an I/O channel interface variant within this product family.
• Approximate Physical Dimensions (W × H × D): Approximately 233 × 160 × 20 mm (9.2 × 6.3 × 0.8 in.) for the 6U VME module format.
• Estimated Shipping Weight: Approximately 1.3–1.5 kg (2.9–3.3 lb) including ESD shielding, front panel protection, and transport packaging.
• What’s in the Box:
  • Motorola MVME104 VME single-board computer
  • Front panel assembly
  • Anti-static (ESD) shielding bag
  • Protective foam packaging
  • EPROM devices when installed
  • Identification label and traceability documentation

Product Introduction

The Motorola MVME104 mounts into a compatible 6U VMEbus chassis, where the P1/P2 connectors establish communication with the VME backplane. Verify the slot position, backplane wiring, and power rail compatibility before installation. The board should slide through the card guides smoothly. Do not force the assembly because the older VME connector contacts are susceptible to mechanical damage.

This controller is a legacy industrial computing asset designed around the Motorola 68010 architecture. The board integrates processor control, shared DRAM, EPROM sockets, serial communication, parallel I/O, timers, watchdog functions, and VME system controller features (which makes it relevant for maintaining older automation and test systems still operating today). Inspect the socketed memory devices, connector pins, electrolytic capacitors, and PCB surface condition before returning stored inventory to service.

Core Technical Specifications

Global Compliance & Industry Certifications

Expected regulatory approvals and compliance considerations for the Motorola include:

• CE Mark compliance when installed within a qualified equipment assembly
• UL/cUL recognition where applicable to the complete VME system
• FCC Class A industrial computing emissions considerations
• IEEE 1014 VMEbus compatibility
• RoHS compliance dependent on manufacturing date and refurbishment history
• ATEX/IECEx suitability only when installed inside a certified hazardous-area enclosure
• Marine approvals such as DNV GL only for specifically qualified systems

For this generation of VME hardware, compliance is generally evaluated at the equipment level rather than the bare circuit board. The chassis enclosure, power supply, grounding scheme, and cable arrangement determine final EMC performance.

Verify specific lot certifications with OEM.

Long-Term Storage & Asset Preservation Guide

Store the inside an anti-static (ESD) shielding bag. The exposed VME edge contacts and socketed EPROM devices require protection from oxidation and contamination.

Inspect all electrolytic capacitors before deployment. These boards are several decades old, and capacitor degradation can create startup failures or unstable operation after extended shelf storage.

Maintain warehouse humidity below 60% RH and avoid temperature cycling. Before installation, record the board revision, EPROM contents, serial number, battery status (if fitted), and visible PCB condition.

Physical Installation Prerequisites

• Install only in a compatible 6U VMEbus chassis.
• Confirm the VME backplane supports the required address and data configuration.
• Verify slot assignment before insertion.
• Use extraction handles and card guides correctly.
• Maintain continuous forced-air cooling through the chassis.
• Leave approximately 50 mm clearance around airflow intake and exhaust paths where practical.
• Confirm chassis protective earth grounding.
• Inspect connector fingers and socketed devices before energization.
• Verify installed EPROM firmware matches the target equipment.

Buyer’s FAQ (Logistics & Compliance Focus)

Q: What HS Tariff Code is commonly used for the Motorola ?

A: VME single-board computers are generally evaluated under HS classifications covering electronic computing assemblies, commonly within HS 8471 categories. The final classification depends on the declared function and importing country’s customs interpretation.

Q: Does Country of Origin affect importing this Motorola board?

A: Yes. COO affects customs records, asset traceability, and supplier documentation. Confirm the origin from the board label, commercial invoice, and available manufacturer records before shipment.

Q: Should shipping insurance be included for the ?

A: Recommended. Although compact, this module contains aging semiconductor components, socketed EPROM devices, and exposed VME connectors. Use ESD packaging, impact protection, and receiving inspection procedures.

Q: Does the include the latest firmware pre-loaded?

A: Firmware depends on the installed EPROM devices. Some units are shipped without EPROM contents or with application-specific firmware from previous systems. Verify the EPROM labels and boot requirements against the target VME installation before commissioning.
