When was electronic ignition introduced?

If talking about Chrysler Electronic, 1972 in 340 cars only.Now I have heard of late 71 340 cars but have no proof of that.

Now here's proff.
Trust me I was doing dist work for everyone in the hood before it came out. When I started working on cars the alternator was the newest thing out. Seriously. I can still remember when my boss and I seen our first set of disc brakes. Ya old but still racing & wrenching. Right now I going to check the engine date on my 71 340 motor and the build date on my charger. Be right back.
