Product Description
The Rockwell 197457-001 is an internal modem card that utilizes the 8-bit ISA (Industry Standard Architecture) bus, a standard expansion interface for personal computers during the late 1980s and early 1990s. This modem was designed to provide data communication capabilities, enabling computers to connect to telephone networks for dial-up access to services like bulletin board systems (BBS), early online networks, and remote data resources. Its internal form factor allowed for a clean installation within the computer chassis, occupying a single ISA slot. As an 8-bit ISA device, the 197457-001 offered compatibility with a wide range of PC and XT-class machines, as well as early AT-class computers. The primary function of this modem was to modulate digital data from the computer into analog signals suitable for transmission over standard phone lines, and demodulate incoming analog signals back into digital data. This process facilitated asynchronous serial communication. Users installing the Rockwell 197457-001 would typically plug it into an available ISA slot and connect a standard RJ-11 telephone cord. Communication software, such as ProComm, Telix, or Windows' built-in terminal programs, was necessary to control the modem and interact with remote systems. The 197457-001 represents a piece of essential hardware that enabled early computer users to connect beyond their local machines and participate in the nascent world of online interaction.
