What is the RoadRunner 1001 ISDN Adapter (PCI Bus W Master Device)?

The RoadRunner 1001 ISDN Adapter is a device that provides ISDN (Integrated Services Digital Network) connectivity for computers, typically via a PCI (Peripheral Component Interconnect) bus. This adapter allows you to connect to ISDN networks, which were commonly used for high-speed internet connections and telecommunications before the widespread adoption of broadband technologies like DSL and fiber optic connections.

• ISDN is a set of communication standards for digital transmission of voice, video, and data over traditional telephone networks.
• The RoadRunner 1001 is likely a specific model of ISDN adapter that supports PCI connections, meaning it slots into the computer's PCI bus for communication with the motherboard and system software.

The "W Master Device" refers to the role of this device in managing or controlling the ISDN connection, and it may support multiple ISDN channels or multiple connections at once.
