Used in Fanuc Series 0 CNC machining centers, this master motherboard is identified on the nameplate as Type A02B-0083-B501 and on the PCB silkscreen as A16B-1010-0150/05A. It is associated with the Fanuc 0M Model A control system and carries the PMC-L (Programmable Machine Controller) designation visible on the board. The serial number on the nameplate reads No. 13427 1987-03, and an asset tag reading 439476 is affixed to the frame. The board was manufactured in Japan by Fanuc Ltd.

The assembly mounts in a metal frame and features a large multi-layer PCB populated with DIP ICs, ribbon cable connectors, and multiple I/O headers along all four edges. Silkscreen-labeled connector groups include CPA4, CPA5, CPA6, and CAP, as well as M1 through M3 and MT2. LED indicators labeled SO, SI, and WDA are present on the board surface. The PCB revision is marked 05A.

This board is a direct replacement candidate for Fanuc 0MA, 0TA, 0PA, and 0GA control systems requiring the A16B-1010-0150 master board assembly. It is compatible with systems using the A02B-0083-B501 system type designation. The item is surplus and is sold as-is with no testing or operational claims.
