Functional Features:​ Parallel processing (no single-CPU bottleneck), <1 ms control cycle, legacy-modern bus bridging, vibration-grade stab connectors.
Working Principle:​ LCP handles network packets; DCP manages I/O timing; MCP closes motor/excitation loop; CMP runs math-heavy load-sharing algorithms.
Materials:​ 7-layer FR-4, gold-edge VME fingers, metal mounting ears.
Installation:​ 6U VME slot in Mark V drive section; seat fully; connect Genius/DLAN cables per GEI-100216.
Precautions:​ Do not swap PROMs with wrong firmware; soft-reset minor faults only; hard-reset on short-circuit recovery; keep conformal coat intact.
