Xircom PE3 adapters are Ethernet adapters designed for computers that miss ISA or PCI slots, or any other "usual" extension port (typically oldish laptop based on 8088-80386 CPUs). The Xircom PE3 adapter is inserted into the parallel (LPT) port of the computer, and requires additional power. The Xircom PE3 serie comes with three models. All models are compatible with the same driver. The only difference is the network connector: * Xircom PE3-10B2 - Thin Ethernet (IEEE 802.3 10BASE-2 with BNC connector) * Xircom PE3-10BT - Twisted Pair (IEEE 802.3 10BASE-T with RJ45 connector) * Xircom PE3-10BC - Both Twisted Pair and Thin Ethernet Available files: BIN pe3drv.exe RESERV Xircom PE3 User Guide.pdf
