Yes, back in the day my "Allen Smart Scope" had a magnetic timing probe. It was a flexible wand style attachment for the Analyzer that allowed you to keep constant digital readings on the scope at all times. The great advantage was you could be adjusting and monitoring other settings without having to hold a timing light. Suppose to be the wave of the future.

It came along during the first years of "CCC" or "Computer Command Control" for you young folks. It had to be set into the Analyzer with a 10 degree offset setting so it could reference TDC.

These were some horrible years for GM and its electronic controlled carburetors, when fuel injection and OBD 1 and OBD 2 came along all this stuff went away.

Sorry for the long post but I thought some might be interested....
