The SunPCi IIIpro coprocessor card is a cost-effective, hardware-based solution for Sun systems that allows the sharing of data, peripherals, and network connections between Microsoft Windows and the Solaris Operating System. In addition to its own Ethernet port, the card also supports the sharing of Sun system's Ethernet ports for increased networking flexibility. Three USB 2.0 ports and a 1394a port, as well as serial and parallel ports, provide support for PC-standard I/O devices such as digital media devices, keyboards, mice, storage, and printers. Windows application support and connectivity on Sun systems alongside Solaris applications saves space, energy, and system management costs, while helping to improve personal productivity. Best of all, the SunPCi IIIpro coprocessor card leverages Sun's biggest strength, reliable and robust network computing.
