Hi Chad,
The article was originally featured in the March 1964 issue of Popular Science.
I will say it required some parts that might be hard to find anymore. At the time it called for 3 TO-36 style transistors. Something could probably be substituted for them now. Also they recommended a special Mallory coil, but alos tol you how you could take a GM Delco coil and remove the primary winds, double them up and rewrap the coil. It stepped up the voltage that way. I know she'll jump a pretty good gap and bites if you get between it...LOL
I've also found and have schematics for other electronic igintion systems. Found one online to build a 6 volt CDI system, positive or negative ground.
