System Board

The V60N is a high-performance system board with a 64-bit architecture. It supports the new Intel Pentium Pro CPU running at 150/166/180/200 MHz and utilizes the Peripheral Component Interconnect (PCI) local bus architecture. The PCI local bus maximizes the system performance by enabling high-speed peripherals to match the speed of the microproces sor with its 120 MB or 132 MB per second transfer rate in burst mode.

The board comes with four ISA and four PCI slots for future expansion. The six 72-pin SIMM soc k ets allow you to upgrade system memory to a maximum of 384 MB.

Onboard I/O interfaces comprise of two UART 16C550 serial ports, a parallel port with ECP/EPP feature, and PS/2 keyboard and mouse ports. These allow the system to support various I/O devices.
