Product Description
The Rockwell SM-24HN/R is an internal modem card specifically designed for the 8-bit ISA expansion slot, common in personal computers of the late 1980s and early 1990s. This modem provides essential data communication capabilities, operating at a speed of 2400 Baud. This speed was a standard for accessing bulletin board systems (BBS), online services, and performing basic file transfers during its operational lifespan. Its internal form factor allowed for a streamlined setup within the computer chassis. As an 8-bit ISA device, the SM-24HN/R offered broad compatibility with a wide range of PC hardware from that era. The modem's primary function was to convert digital data from the computer into analog signals that could be transmitted over standard telephone lines, and vice versa. This enabled users to establish dial-up connections to remote modems, facilitating communication and access to information networks. To utilize the Rockwell SM-24HN/R, users needed to install the card 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 SM-24HN/R represents a fundamental component of early personal computing connectivity, enabling users to venture into the nascent world of online interaction.
