USRobotics 56678-1 Modem Isa, Sportster 0467, D 00056678 Rev A00, (B.31)

Product Description

The USRobotics 56678-1 is an internal modem card designed for installation in the ISA (Industry Standard Architecture) expansion slots of older personal computers. Identified by its part number and associated with the popular Sportster line, this modem facilitated dial-up communication, enabling users to connect to the internet, bulletin board systems (BBS), and other remote computer resources over standard telephone lines. The '0467' designation likely refers to a specific model or feature set within the Sportster family. This particular model specifies a hardware revision 'Rev A00' and a firmware version '(B.31)', indicating the specific iteration of the hardware and its embedded software. These details are important for compatibility and functionality, especially in legacy systems where specific hardware configurations are critical. The modem's primary function is to modulate and demodulate signals, converting digital data from the computer into analog signals for transmission over phone lines and vice versa. As an ISA card, it is intended for use in computers that predate the widespread adoption of PCI or USB interfaces. It provides essential data and fax capabilities, making it a valuable component for enthusiasts of vintage computing or for maintaining older systems that require dial-up connectivity. Installation involves physically inserting the card into an available ISA slot within the computer's chassis.
