	# ~~Spray WD40 on~~ the back ~~of the board (not kidding).~~		# Some flux are water soluble so just rinse the back side in the sink with some soapy water and an old tooth brush. Try not to get water on the front side. Little water is okay.

	~~== Storage ==~~

	If you don't plan on using ISA Backplane for an extended period of time it is recommended to take out the clock battery out of any processor boards and store the entire computer in a dry place. Depending on where you live typically garages or basements are not dry places especially in the North East US.

			== Jumper Settings ==

			The board has 4 jumper settings. J1 is to enable the voltage regulator and the remaining are for the LED display configuration seen in the section below. Pin 1 of the jumper is the one shaped like a square.

			If you purchased this as a kit from my eBay store then then it includes the CD4511 decoder chip and the settings are:
			* J1 = 2-3 - enable -5V
			* J2-J4 = 1-2, 2-3, 1-2

	== LED Display Configuration==		== LED Display Configuration==

			If you are using the CD4511 decoder and you have made the jumper settings above you can skip this section.

	The ISA Backplane board supports a variety of 7-segment decoders and common anode / common cathode type LED displays. Please use the following table to determine the proper jumper pin configuration for J2 J3 and J4		The ISA Backplane board supports a variety of 7-segment decoders and common anode / common cathode type LED displays.
