IBM 82G5772 4-Ports 512KB Cache Arctic ISA Multiport Card

Product Description

The IBM 82G5772 is a multiport expansion card that utilizes the ISA (Industry Standard Architecture) bus, indicating its design for older computer systems and servers. This card is equipped with four ports, which can typically be configured as serial (RS-232) or parallel ports, depending on the specific implementation and system requirements. The inclusion of 512KB of cache memory helps to buffer data transfers, potentially improving performance for I/O intensive tasks associated with these ports. This card serves the purpose of adding essential connectivity to systems that may have limited built-in ports or require specialized connections. In environments still relying on legacy hardware or peripherals that communicate via serial or parallel interfaces, the 82G5772 provides a crucial expansion solution. Its ISA interface means it is compatible with older motherboards that feature these expansion slots, bridging the gap for systems that cannot be easily upgraded to modern bus architectures like PCI or PCIe. Given its specifications, the IBM 82G5772 is likely intended for specific IBM server models or workstations from an era when ISA was prevalent. It would have been used to connect devices such as modems, printers, scanners, or specialized industrial equipment that relied on these older communication standards. The 512KB cache suggests a focus on reliable data handling for these connected peripherals.
