Description

AT&T 008-0078254 Socket 5 Motherboard System Board Riser Required ISA PCI

AT&T system board designed for Socket 5 Intel Pentium processors. This proprietary form factor board requires a riser card to access ISA and PCI expansion slots.

Specifications & What's Included

  • Socket Type: Socket 5 (Intel Pentium compatible)
  • Chipset: VLSI
  • Memory: Multiple SIMM slots
  • Integrated Ports: PS/2, Serial (x2), Parallel, VGA
  • Expansion: ISA and PCI via riser card (riser not included)
  • Form Factor: Proprietary (requires riser card)

Applications

This board was used in AT&T Globalyst desktop systems from the mid-1990s Pentium era. Socket 5 motherboards supported first and second generation Pentium processors and were common in business and industrial computing environments. The AT&T Globalyst line served corporate and institutional applications requiring standard PC architecture with AT&T-integrated components.

Condition: Used
This AT&T 008-0078254 Socket 5 Motherboard has been tested and confirmed to boot to BIOS when the proper components are installed. It is in good working order. Note that this board has no connector for an 80-pin SCSI Hot Swap hard drive. A riser card is required for expansion slot access — none is included. The board shows typical light wear consistent with previous use but is in solid physical condition. Please view our photo set and contact us if you have any questions.
