Applications
Token Ring was IBM's LAN standard that competed with Ethernet through the late 1980s and 1990s, using a token-passing ring topology that was common in corporate and financial environments that standardized on IBM infrastructure. The Dell TR-APR was built for Dell Latitude laptops of that era — models such as the Latitude XPi and similar APR-compatible units — and allowed them to join an existing Token Ring network at a desk while also gaining access to serial, parallel, and PS/2 ports for printers and other peripherals. Token Ring networks are largely obsolete today, having been superseded by Fast Ethernet and Gigabit Ethernet, but this replicator remains relevant to technicians maintaining legacy IBM environments, collectors of 1990s-era networking equipment, and anyone needing a compatible docking solution for an original Dell APR-equipped Latitude laptop.
This Dell TR-APR 90241 Token Ring Port Replicator has been inspected and is in good used condition. The housing is intact with light surface wear consistent with age. All rear ports — including the PS/2, DB9 serial, parallel, RJ-45, and Token Ring DB25 connectors — appear clean and undamaged. The high-density docking connector shows no bent pins. The bottom label is legible, confirming Rev A02 and power specs. Please view our photo set and contact us if you have any questions.
