Description

Adaptec AHA-2742W EISA SCSI Adapter Card 16-Bit

The Adaptec AHA-2742W is a 16-bit EISA SCSI host adapter designed for systems from the late 1980s and early 1990s. It provides a bridge between the EISA expansion bus and SCSI devices, allowing connection of hard drives, CD-ROM drives, tape backup units, and other SCSI peripherals to legacy computer systems. The AHA-2742W was a widely deployed adapter in this era and supports both internal and external SCSI devices via standard 50-pin connectors.

  • Form Factor: Half-length EISA expansion card
  • Supports both internal and external SCSI devices
  • Compatible with EISA-based systems from the 1990s era

Applications

This adapter was the standard SCSI controller for EISA-based computers throughout the 1990s, commonly found in Intel 486 and Pentium systems, workstations, and servers. It enabled connection to the growing library of SCSI peripherals that dominated enterprise and high-performance computing during that era—hard disk arrays, optical drives, and tape backup systems relied on adapters like this for reliable data storage and recovery. Today, it remains sought after for legacy system restoration, retro computing projects, and museum exhibits that require authentic 1990s-era hardware. The AHA-2742W is compatible with any EISA slot on systems such as Compaq ProLiant servers, Hewlett-Packard systems, and other enterprise and OEM platforms that featured EISA architecture.
