Product Description
The IBM 83X9144 is a specialized network adapter card designed to provide Token Ring connectivity for older IBM computer systems. It features a single DB-9 connector, which was a common physical interface for Token Ring networks. The adapter supports a data transfer rate of 4 Megabits per second (Mbit/s), which was standard for many Token Ring implementations of its era. This card is crucial for systems that require integration into legacy Token Ring network infrastructures. This adapter card is notable for its support of both ISA (Industry Standard Architecture) and Micro Channel Architecture (MCA) bus types. This dual support indicates its design for a range of IBM personal computers and workstations from the late 1980s and early 1990s, which often featured one or both of these bus standards. The ability to function on either bus makes it a versatile option for maintaining or upgrading older IBM hardware. The primary function of the IBM 83X9144 is to enable a computer to connect to and communicate over a Token Ring network. Token Ring was a popular local area networking technology developed by IBM, known for its deterministic access method and reliability. This adapter would have been used in environments where IBM systems were prevalent and Token Ring was the chosen networking standard for departmental or office connectivity.
