 ==== About ====
-ISA Backplane board was designed by Sergey Malinov ([[http://www.malinov.com/Home/sergeys-projects|http://www.malinov.com/Home/sergeys-projects]]) and is designed to be used together with the Xi 8088 processor board, but it can be used with other ISA SBC boards. In addition to eight parallelly connected ISA slots this backplane includes an ATX power on/off circuit, a Port 80h POST display, a -5V regulator (most ATX power supplies don't supply -5V, but it can be required for some older ISA cards), serial port header, and a prototyping space.
