Applications

Riser cards like the D5063-8740 were a standard solution in the 1990s–early 2000s for compact desktop PCs where the chassis height did not allow expansion cards to mount directly to the motherboard in the conventional horizontal orientation. The HP Vectra VL was HP's mainstream business desktop line of that era, and this riser was the mechanism through which users could add ISA peripherals — such as modems, sound cards, and older I/O controllers — alongside PCI cards like network adapters, SCSI controllers, and video cards. Today this board is sought primarily as a direct replacement part for HP Vectra VL systems still in service, as well as by collectors and technicians maintaining legacy HP business desktop fleets. Because the Vectra VL used a proprietary riser connector and slot arrangement, the D5063-8740 is not interchangeable with generic aftermarket riser cards.
