I have two 555s. Both need a lot of work, unfortunately. Someday.
Oh...wow. That's amazing
Did you see the LT app note of Jim Williams' authorship in which he presented a single picture of an oscilloscope CRT with both a time-domain and a frequency-domain plot on it? He added a footnote suggesting that people should try to figure out how he did that. It was with a 555, with a standard oscilloscope plugin for one gun and a spectrum analyzer plugin for the other gun. Great stuff.
Yes, that's a classic! App note 35, page 16: http://cds.linear.com/docs/en/application-note/an35f.pdf
