FORCE SYS68K/CPU-30BE/16-REV3 – 32-Bit VMEbus CPU Board | SYS68K Platform
Engineering Background: The SYS68K series was developed by FORCE Computers (Germany) as a high-reliability VMEbus single-board computer family for demanding industrial, defense, and process-control environments. Built around the Motorola MC68030 processor, the SYS68K/CPU-30BE/16 delivers deterministic real-time performance within the IEEE 1014-1987 (VMEbus) standard architecture. Revision 3 incorporates refined bus arbitration logic and improved thermal management over earlier board revisions.
Product Positioning: This board is the preferred CPU node for legacy VME rack systems requiring a proven 32-bit CISC processor with on-chip MMU and FPU coprocessor support. It is directly applicable to SCADA front-end controllers, CNC machine tool axes controllers, and scientific instrumentation platforms where long-lifecycle component availability is critical.

System Architecture & Signal Flow
The SYS68K/CPU-30BE/16-REV3 operates as the VMEbus System Controller (Slot 1) or non-system-controller node. The MC68030 CPU interfaces to local DRAM/SRAM via a dedicated local bus, while the VMEbus interface ASIC handles all P1/P2 connector transactions. The on-chip MMU manages address translation for multi-process operating systems. The MC68882 FPU coprocessor communicates via the MC68030 coprocessor interface, offloading floating-point operations from the integer pipeline. Bus arbitration supports RRS (Round-Robin Scheduling) and PRI (Priority) modes configurable via onboard DIP switches.

Technical FAQ
Q: Is this board compatible with VxWorks RTOS?
A: Yes. The MC68030 with integrated MMU is a supported target for VxWorks 5.x and OS-9. BSP availability depends on your specific rack configuration.
Q: Can this replace an earlier REV 1 or REV 2 board?
A: In most cases yes — REV 3 is backward-compatible at the connector and bus level. Verify EPROM firmware version compatibility with your system integrator.
Q: What operating systems are supported?
A: OS-9 (Microware), VxWorks (Wind River), LynxOS, and bare-metal firmware are all documented for the SYS68K/CPU-30 family.
Q: Do you provide a test report?
A: A functional test summary is available upon request. Contact us before placing your order if a formal test report is required.
Q: What is the lead time for international orders?
A: In-stock items ship within 2–3 business days. DHL Express international delivery typically 3–7 business days depending on destination.
