A CRT Data Interface board labeled with part number 501-03895-02 (revision 02), this vintage industrial PCB is designed for use in CNC machine control systems requiring a dedicated display interface between the control electronics and a CRT monitor. The board carries a secondary assembly designation of 502-03098-01, visible on the bottom edge of the component side. Construction is through-hole with a densely populated array of DIP ICs, passive components, and edge connectors along both sides of the board, indicating integration into a backplane or card cage configuration. Notable ICs visible include Japan-sourced devices such as the H4 5505SP-2 BB45SP and multiple 74-series logic packages. Multiple sub-assembly stickers are present on several IC positions, including labels referencing 502-03105-01, 502-03163-01, 502-03164-01, 503-70073-03, 502-70205-04, and 88135-01 / 88137-01, suggesting component-level traceability. The board features gold-plated edge connectors on two sides, consistent with a dual-slot card rack installation. A date code of M.1017.0878 is visible on the bottom edge, along with a barcode serial number label. This board is suited for facilities maintaining legacy CNC equipment that relies on CRT-based operator interfaces and require period-correct replacement electronics.
