Re: tunnel diodes retrace lines in curve tracer

My understanding is that by the 1970's or so, TD's were obsolete because most of the practical circuits that used them could be done cheaper with modern transistors and IC's.
TD's could do certain things with a bare minimum parts count, but that wasn't important enough, with the parts count (inside of IC's) exploding in other areas.
Also note that many of the interesting apps for TD's involve inductors, but inductors are not cheap.

I could be wrong...
