Product Description
The Rockwell KB3108-05 is an internal modem card designed for installation into the 8-bit ISA (Industry Standard Architecture) expansion slots found in many personal computers from the late 1980s and early 1990s. This particular model is specified for data communication at a speed of 2400 Baud, a common standard for accessing bulletin board systems (BBS), online services, and performing basic file transfers during that period. Its internal form factor allowed for a clean integration within the computer case, occupying a single ISA slot. As an 8-bit ISA device, the KB3108-05 offered compatibility with a wide range of PC and XT-class machines, as well as early AT-class computers. The modem's fundamental role was to modulate and demodulate signals, enabling digital data from the computer to be transmitted over analog telephone lines and received signals to be converted back into digital data. This facilitated asynchronous serial communication. To use the Rockwell KB3108-05, users would typically install the card into an available ISA slot and connect a standard RJ-11 telephone cord. Communication software, such as MS-DOS terminal programs or early Windows applications, was required to manage the modem's operations, initiate dial-up connections, and interact with remote systems. The KB3108-05 represents a foundational piece of hardware that enabled early computer users to connect and communicate remotely.
