Product Description
The IBM 83X7538 is a network adapter designed to provide Token Ring connectivity through a single DB-9 port. It operates at a speed of 4 Megabits per second (Mbit/s), which was standard for many Token Ring implementations. This adapter is specifically built for systems that utilize the Micro Channel Architecture (MCA) bus, a proprietary expansion bus developed by IBM for its PS/2 line of computers. This adapter allows compatible IBM MCA systems to join a Token Ring network, enabling data exchange and communication within that specific network topology. The DB-9 connector is characteristic of the physical interface used for Token Ring networks, often connecting to a network cable via an adapter or directly. As a legacy component, the IBM 83X7538 is crucial for maintaining or restoring network functionality in environments that still rely on Token Ring infrastructure and IBM MCA-based hardware. Its specific design for the MCA bus ensures proper integration and performance within those systems.
