Product Introduction
Your VME64x backplane is still solid, but the CPU in slot 1 just gave up the ghost. The GE VMIVME-7807 is the drop-in life support your rack needs. It’s a 6U single-board computer packing a Pentium M processor (up to 1.8GHz) and dual Gigabit Ethernet, bridging the gap between legacy VME wiring and modern network diagnostics. You keep your expensive I/O cards and terminal blocks; this board just gives them a faster brain.
The VMIVME-017807-413000 suffix isn’t just a random number; it defines your memory and flash configuration. This specific variant supports up to 1.5GB of DDR SDRAM and optional VITA 31.1 routing for backplane GigE. Honestly, trying to retrofit a newer CPU into an old VME chassis is a headache. This board lets you refresh the compute layer without re-certifying the entire safety system or rewiring the panel. It’s the pragmatic choice for keeping 20-year-old infrastructure alive.
Troubleshooting Quick Reference
- No Boot / Blank Console: 70% chance it’s a RAM seating issue. Reseat the SODIMM. Check the soldered memory for cold joints if you’re handy with a microscope.
- GigE Port Not Linking: 80% chance of DIP switch misconfiguration. Verify P0/P2 routing switches match your backplane wiring. VITA 31.1 requires specific P0 pinouts.
- System Resets Under Load: Power supply sag. Measure +5V rail at the board during max load. If it drops below 4.75V, your PSU is tired, not the CPU.
- CompactFlash Not Detected: Check the IDE ribbon cable. These connectors get brittle with heat cycles. Also verify BIOS boot order settings.
- Overtemp Shutdown: Airflow is critical. Verify 450 LFM at the exhaust side. If the fan is dead or filters are clogged, the Pentium M will thermal trip fast.

Application Scenarios & Pain Points
- Gas Turbine Control Systems: Legacy Mark* controllers needing network upgrades. Pain point: OEM upgrades cost $100k+. The VMIVME-7807 adds GigE for remote diagnostics at a fraction of the price.
- Petrochemical Batch Processing: VME64x racks running 24/7. Pain point: Finding 1.8GHz Pentium M boards is getting impossible. This specific 413000 config matches existing memory maps.
- Marine Radar/Navigation: VME-based sensor fusion. Pain point: Salt air kills connectors. The VMIVME-7807’s conformal coating and rugged VME form factor survive where commercial PCs fail.
