IT5A 586/686 Processor/AGP Based ATX Mainboard  

This is ABIT's premier Socket 7 (586) motherboard of the future, sometimes called a Super 7TM mainboard. Based on the ALi Aladdin V chipset it includes an AGP slot for the latest in performance 3D graphics. This mainboard is designed for use at 100MHz Front Side Bus speeds. Compared with today's 66Mhz FSB speeds, this board is a true technological advancement and has official support for the future AMD K6 3D CPU's as well as other 586 CPU's from Intel, AMD, Cyrix and IDT.
