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.\u003c\/p\u003e\n\n\u003cp\u003eStock # 0226-567\u003c\/p\u003e","brand":"Gidding \u0026 Lewis","offers":[{"title":"Default Title","offer_id":48884991197424,"sku":"m00567","price":1999.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0797\/6648\/7280\/files\/74BE1F9E-B9B1-4410-9E5B-0145D072659C.jpg?v=1771863673","url":"https:\/\/mroexchange.com\/products\/gidding-lewis-board-501-03895-02-502-03098-01-0226-567","provider":"MRO Exchange","version":"1.0","type":"link"}
