Used in Bridgeport Series II CNC milling machines, the Bridgeport Servo Control Board carries OEM part number 501-04303-02, with assembly reference 502-03417-02, REV2, dated 1/89. The board is labeled "SERVO CONTROL" directly on the PCB silkscreen and is associated with the SBX3 designation common to Bridgeport Interact platform controls. The board features a DAC811AH digital-to-analog converter, a dense population of HCMOS logic ICs including MM74HC and MC74HC series devices from multiple manufacturers, and NEC memory components visible on the component side. Multiple edge connectors are present along the bottom and right edges for integration into the machine control backplane. The reverse side shows a multilayer through-hole design with gold-plated edge fingers. This is a large-format board measuring approximately 14 by 10 inches. Serial number A80775 is visible on the barcode label. The board dates to January 1989 and is consistent with the Bridgeport Series II Interact CNC control architecture of that period. MPN 501-04303-02 is the primary OEM identifier. Compatible machine platforms and exact system requirements should be verified against Bridgeport Interact Series II service documentation prior to installation.
