Packard Bell 148537 3 PCI 3 ISA Riser Card 52F53 Rev C Desktop PC Expansion

Packard Bell 148537 3 PCI 3 ISA Riser Card 52F53 Rev C Desktop PC Expansion

The Packard Bell 148537 is a combination PCI/ISA riser card that provides three PCI and three ISA expansion slots for compatible Packard Bell desktop systems. The board carries the silkscreen identifier 52F53 REV:C and connects to the motherboard via a riser edge connector, orienting expansion cards parallel to the main board — a common design in slim and mid-tower Packard Bell desktop PCs of the mid-1990s. This is new old stock, unused and uninstalled.

Applications

Riser cards like this one were standard in slim-desktop and space-saving tower PCs of the mid-1990s, where the chassis did not allow full-height expansion cards to mount directly and vertically off the motherboard. Instead, the riser card attaches to the motherboard's riser slot and rotates the expansion cards 90 degrees so they lie flat, parallel to the motherboard — fitting within a lower-profile enclosure. This board was designed for specific Packard Bell desktop models of the 1995–1997 era that used a proprietary riser form factor. The combination of three PCI and three ISA slots reflects the transitional period when ISA cards (sound cards, modems, I/O controllers) were still common alongside the newer PCI bus for graphics and faster peripherals. Today these boards are sought primarily for servicing or restoring Packard Bell systems of that generation, as replacement riser cards are difficult to source.
