Applications

MCA riser cards were used in IBM PS/2 systems to expand internal expansion slot capacity. These cards allowed users to add additional MCA-compatible cards such as network adapters, storage controllers, or other peripherals when available slots on the motherboard were occupied. Riser cards mounted perpendicular to the main board, redirecting expansion cards horizontally. Commonly found in PS/2 Models 50, 60, 70, and 80 configurations where internal card density required optimization.

Condition: Used
This IBM 27F4626 MCA Riser Card has been inspected and is in good used condition. It was pulled from a working environment where it was in use and functional. The PCB shows light surface wear typical of a card that has been installed and removed, but there is no visible physical damage, broken traces, or bent connector pins. The edge connectors and MCA expansion slots appear clean. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
