Applications
Socket 8 motherboards were introduced by Intel in 1995 to support the Pentium Pro processor, a high-performance chip aimed at workstation and server applications. The Pentium Pro was notable for integrating the L2 cache directly into the processor package, giving it exceptional performance for 32-bit workloads — making boards like this one common in mid-to-late 1990s server rooms, CAD workstations, and high-end desktops. Socket 8 was also the last socket to support the Pentium II Overdrive processor, which allowed some systems to be upgraded beyond the original Pentium Pro. Today these boards are sought by vintage computing enthusiasts, collectors building period-correct 1990s workstations, and technicians restoring legacy server or industrial systems that originally ran on the Pentium Pro platform. The onboard Adaptec SCSI controller makes this board particularly useful for systems requiring SCSI storage connectivity without a separate expansion card.
This Acer 48.59101 Socket 8 Motherboard is being sold AS-IS and has not been tested at our facility. No functionality is guaranteed. The board includes the VRM module (header 76H1815) and RAM (M11A 96105-1) as shown in the photos.
