Today, I teach my last class of the term for MIT 6.331 (Advanced Circuit Techniques). This term has been particularly bittersweet, since every other time that I've taught this class over the past twenty years, Jim has flown out and given a guest lecture. These lectures were always interesting, entertaining, and well attended.
The last time I taught this class (two years ago), Jim came out and gave a lecture on the history of the Hewlett Packard 200A oscillator. He also told the tale of the acquisition of his own (very early model) HP 200A, which is a great story (see Figure E2 in App Note 70). One of the attendees, my friend Anson Whealler, took this photo right before the lecture.
We miss you, Jim.
