Product Introduction
FORCE SYS68K-SASI-1 300000 is a Force Computers single-board computer (SBC) built on the SYS68K VMEbus platform. It uses a Motorola 68K-series industrial CPU and provides multi serial/parallel I/O, memory expansion (DRAM/SRAM/EPROM/Flash), and VMEbus connectivity for embedded control in industrial automation, defense, and communications systems.
This board is typically chosen for legacy VME-based systems where exact hardware match and bus behavior are critical. Stock is limited to discontinued/surplus channels, and most listings are used or refurbished with testing. Verify the exact revision and firmware before ordering.

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/status before swap | Verify 5 V and backplane seating first |
| Boot hangs early or resets | CPU fault, memory fault, or OS/firmware error | ✅ High | Observe reset behavior and any status LEDs; try a known-good slot | Treat as likely board-level failure |
| Serial ports unresponsive | Wiring issue, baud mismatch, or port hardware fault | ✅ Medium | Check cabling, 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 |
Contact technical support with photos of the board, connectors, LEDs, and any console or diagnostic logs if the fault is unclear.
Frequently Asked Questions (FAQ)
Q: Is the SYS68K-SASI-1 300000 still in production?A: No. It is an obsolete Force Computers part, discontinued by the manufacturer. Supply is limited to surplus, refurbished, or used-tested stock.
Q: Can I use this as a direct replacement for another SYS68K SBC?A: Only if the CPU type, clock speed, memory configuration, I/O map, revision, and firmware match your installed system. Verify the exact rack and firmware version before ordering.
Q: Is it hot-swappable?A: No. Power down the rack before removal. Pulling a VME board live can damage the board or the backplane.
Q: Will my existing OS/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 on the replacement.
Q: What condition should I expect?A: Most stock is used or refurbished (tested). Some sellers may offer “never used” surplus, but factory warranty may not apply; a seller warranty typically covers the item.
Q: Why is this board limited/expensive?A: It is legacy hardware with no factory support and limited availability. The price reflects age, scarcity, and the testing/refurbishment effort.
Q: What should I check before installing a replacement SYS68K-SASI-1?A: Match the revision, inspect the edge connector, verify backplane power, and photograph every jumper/strap on the original board before removal.
