Connectors

There are several connectors on the board for switches and indicator lights

from the system case. The connectors are made of the same components

as the jumper switches. There are also connectors for the on board I/O ports

and the leads from a 5-volt system power supply.

IMPORTANT: Ribbon cable should always be connected with the red stripe

on the Pin 1 side of the connector. The Four Corners of the

connectors are labeled on the NUPRO-710. Pin 1 is the side

closet to the power connector on hard drivers and floppy

drivers. IDE ribbon cable must be less than 18in. (46cm),

with the second drive connector no more than 6in. (15cm)

From the first connector.
