Description
IBM 88G4248 Riser Card ISA Expansion 3-Slot PC Server Motherboard Adapter
The IBM 88G4248 is an ISA riser card designed for use in IBM PC Server systems. It extends the motherboard's ISA bus slots at a right angle, allowing full-length expansion cards to be installed in space-constrained tower or desktop server chassis. The card features three ISA expansion slots and a keyed edge connector for direct motherboard installation.

Applications
ISA riser cards like the IBM 88G4248 were a common solution in 1990s IBM PC Server and desktop tower chassis designs, where space constraints prevented full-length ISA cards from being installed vertically off the motherboard. By redirecting the ISA bus slots horizontally or at a right angle, riser cards allowed legacy ISA peripherals — such as serial/parallel I/O cards, network adapters, sound cards, and proprietary IBM expansion cards — to seat properly within the case envelope. This card is primarily of interest today to technicians maintaining legacy IBM PC Server hardware or hobbyists restoring IBM systems from the mid-to-late 1990s ISA era.
This IBM 88G4248 ISA Riser Card has been inspected and appears to be in good used condition. The PCB is clean with no visible cracks, burn marks, or broken traces. Minor scuffing and shelf wear consistent with prior installation are present, as visible in the photos. It was pulled from a working IBM server environment where it was previously in use, though it has not been powered or tested at our facility. Please view our photo set and contact us if you have any questions.
