Product Introduction
The Motorola MVME2400-0361 is a reliable VMEbus SBC built on the PowerPlus II architecture. It uses a 366MHz PowerPC 750 processor with 1MB backside L2 cache for deterministic control.
This replacement module supports up to 512MB ECC SDRAM and dual PMC expansion slots. It handles aerospace, defense, and industrial tasks with VME64 compatibility.

Quality Control Process
We inspect every surplus stock unit with care. First, we verify the 366MHz MPC750 boots and passes POST diagnostics. Next, we run memory stress tests on the ECC SDRAM to catch bit errors. We validate the 8MB flash and 8K NVRAM integrity, including battery voltage checks. Dual PMC slots get functional verification with known-good mezzanine cards. Finally, we pack the SBC in anti-static shielding.
Replacement Pitfall Guide
❗ Check NVRAM Battery Voltage. The 8K NVRAM relies on an onboard battery for retention. Old stock often has dead batteries. Test voltage before installing to avoid config loss.
❗ Verify PMC I/O Routing. The dual PMC slots support both front-panel and P2 rear I/O. Wrong jumper settings will disable rear connectors. Consult the manual before wiring.
❗ VME64 Backplane Compatibility. This SBC uses VME64 5-row connectors. Older 3-row VME32 backplanes work but limit bandwidth. Confirm your chassis supports VME64 signaling.
❗ L2 Cache Enablement. The 1MB backside L2 cache must be enabled in firmware. Disabled cache causes severe performance drops. Verify BSP settings after installation.
Keep these in mind and you’ll cut 90% of rework time.
