Product Description
The Rockwell KB5670 is an internal modem card that utilizes the 8-bit ISA (Industry Standard Architecture) bus, a prevalent interface for expansion cards in personal computers during the late 1980s and early 1990s. This modem was engineered to provide data communication capabilities, allowing computers to connect to telephone networks for dial-up access to services like bulletin board systems (BBS), email, and early online networks. Its internal design meant it occupied a slot within the computer, offering a space-saving and integrated solution. As an 8-bit ISA device, the KB5670 was compatible with a broad spectrum of PC and XT-class machines, as well as early AT-class computers. The core 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 enabled asynchronous serial communication. Users installing the Rockwell KB5670 would typically plug it into an available ISA slot and connect a standard RJ-11 telephone cord. The modem would then be controlled via communication software, requiring appropriate drivers for the operating system (such as MS-DOS or early Windows versions) to recognize and operate the hardware. The KB5670 represents a piece of essential hardware that facilitated early computer networking and remote access.
