Product Introduction
Force SYS68K CPU-6VA is a legacy Force Computers VME CPU board built on the SYS68K platform with a Motorola MC68010 processor running at 12.5 MHz and 512 KB system RAM. It is used in older VME-based industrial control, embedded automation, and test equipment racks.
This board is chosen primarily for exact hardware replacement in legacy SYS68K systems where firmware, timing, and bus behavior must match the original design. Stock is limited to surplus/used channels, and many listings show it as used but tested.
Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No boot activity at power-up | Missing backplane power, failed board, or bad VME slot | ✅ High | Measure rack supply rails and check board LEDs before swap | Verify 5 V and backplane seating first |
| Boot hangs early or resets | 68010 CPU fault, RAM issue, or firmware (VMEPROM) error | ✅ High | Observe reset behavior and any status LEDs; try a known-good slot | Treat as likely board-level failure |
| No peripheral response (SCSI/serial) | Cable/termination issue, baud mismatch, or port hardware fault | ✅ Medium | Check cables, termination, and terminal settings; run loopback test | Fix external side first, then suspect board |
| Intermittent crashes | Thermal issue, aging components, or unstable power | ✅ High | Monitor board temperature and test with stable rack power | Consider board replacement if instability persists |
| VME bus errors | Slot contact issue, backplane fault, or address conflict | ✅ High | Reseat board, inspect edge connector, verify address map | Check rack integrity and jumper/strap settings |
If the fault is unclear, contact technical support with photos of the board, connectors, LEDs, and any console or diagnostic logs.
Frequently Asked Questions (FAQ)
Q: Is the SYS68K CPU-6VA still in production?A: No. It is an obsolete Force Computers part, and supply is limited to used or tested surplus stock.
Q: Can I use this as a direct replacement for another CPU-6 variant?A: Only if the processor type, clock speed, memory size, firmware, and revision match your installed system. Confirm the exact rack, revision, and firmware before ordering.
Q: Is it hot-swappable?A: No. Power down the rack before removal. Pulling a VME CPU live can damage the board or backplane.
Q: Will my existing configuration survive a swap?A: Not guaranteed. If your system stores configuration or boot parameters on the board or in local firmware, back them up first and match jumpers/straps and firmware versions.
Q: Why is this board priced around $2,100?A: It is legacy hardware sold as used or tested surplus with limited availability. The price reflects age and scarcity, not a premium feature set.
Q: What condition should I expect?A: Most stock for this part is used or tested used. Confirm whether the seller offers used, refurbished, or “new old stock” before purchase.
Q: What should I check before installing a replacement CPU-6VA?A: Match the revision, inspect the edge connector, verify backplane power, and photograph every jumper/strap on the original board before removal.
