Product Description
The IBM 83X7487 is a legacy network adapter specifically designed to provide Token Ring connectivity for IBM Personal System/2 (PS/2) Model 50 computers. This adapter allows these older systems to connect to a Token Ring local area network, a popular networking technology in the past. Operating at a data transfer rate of 4 Megabits per second (Mb/s), this adapter facilitates communication within the Token Ring network. Token Ring networks are known for their deterministic access method, which ensures fair access to the network for all connected devices, preventing collisions. Given its compatibility with PS/2 Model 50, this adapter likely utilizes the Micro Channel Architecture (MCA) bus, which was characteristic of IBM's PS/2 line. The 83X7487 is a specialized piece of hardware for maintaining or establishing network connections in environments still utilizing Token Ring infrastructure with compatible IBM systems.
