Description
The IBM 22F9380 is a specialized network adapter card designed to bring Token Ring network connectivity to IBM systems that utilize the Micro Channel Architecture (MCA). This proprietary bus architecture was prevalent in IBM's PS/2 line of computers and other compatible workstations during the late 1980s and early 1990s. The adapter card features a single DB-9 connector, which is characteristic of serial communication ports, and interfaces with the Token Ring network topology. This adapter is crucial for maintaining or establishing network connections in environments that still rely on Token Ring technology. Token Ring networks, developed by IBM, were known for their deterministic access method, which provided predictable performance, making them suitable for certain business-critical applications. The 22F9380 supports both 4 Mbps and 16 Mbps data transfer rates, allowing it to adapt to different network speeds within a Token Ring setup. Installation of the IBM 22F9380 requires an available Micro Channel slot on the motherboard. It is intended for users who need to integrate legacy IBM hardware into existing or legacy network infrastructures. Given the obsolescence of Token Ring and MCA, this adapter is primarily of interest for archival, specialized industrial, or legacy system maintenance purposes.
