Giddings and Lewis Servo Control 486 circuit board, part number 501-04707-00, revision R5, dated 10/95. Also referenced by assembly sticker 503-25209-01. This large-format, multi-layer PCB was produced by Giddings and Lewis for use in their 486-based CNC machine tool control systems, including horizontal boring mills and machining centers equipped with the G&L Centurion and related control platforms.

The board features a dense population of through-hole and surface-mount components including multiple CHIPS-branded processor ICs, oscillator circuits, DIP logic packages, and numerous proprietary G&L subassembly ICs identified by 502-series part numbers. Three SBX expansion connectors are present along the left edge, consistent with the G&L modular backplane architecture. The board was manufactured in the United States.

This part number appears in active US surplus markets as a direct replacement for failed or damaged servo control boards in G&L 486-generation CNC systems. It is suited for facilities maintaining legacy Giddings and Lewis machine tools and requiring a spare or replacement servo control board. Compatibility should be confirmed against the specific machine control configuration prior to installation.
