Description
The IBM 83X7488 is a legacy network interface card (NIC) specifically designed for IBM systems that employ the Micro Channel Architecture (MCA). This adapter facilitates network connectivity using the Token Ring protocol, a widely used networking technology in enterprise environments during the late 1980s and 1990s. Operating at a data transfer rate of 4 Megabits per second (Mbps), the 83X7488 provides the necessary hardware interface for connecting compatible IBM computers to a Token Ring network. The Micro Channel bus was IBM's proprietary expansion bus architecture found in their PS/2 line of computers and some other server systems, offering higher performance and bus mastering capabilities compared to contemporary ISA buses. This adapter is characterized by its specific MCA connector and typically features a DB-9 connector for the Token Ring cable. It represents a piece of networking history, essential for maintaining or restoring connectivity in legacy IBM environments that still rely on Token Ring infrastructure. Its functionality is focused solely on enabling network communication within the constraints of the Token Ring standard and the MCA bus.
