Patents for multi-spark ignition system

[m_mcdonald at marx.ENET.dec.com]

	One person on this list has made available a schematic from
	the company that makes the most popular (and the only?)
	multi-spark ignition system.  As I recall, it's the MSD system
	made by Autotronic Controls of El Paso, Texas.

	The company has two patents on this product.  Both of them
	contain schematic diagrams and a detailed description of how
	a multi-spark ignition system works.  If you want both of
	these patents, send a check for $6.00 payable to the Patent
	and Trademark Office.  Send it to

	Patent and Trademark Office
	Washington, DC  20231

	along with your name and address and these patent numbers:

	3,926,165
	4,131,100

	The patents should arrive in 3-4 weeks.

	The respective dates of the patents are December 1975 and
	December 1978.  Since patents issued then are valid for 17
	years, both have expired now.
