Yes, indeed, I can write code with one hand and wire-wrap with the other. “Prove it,” you say. Well, I did in the late 80s.

After several years working on test equipment purchased by IBM, I decided it was time to take the plunge. A different department in IBM was developing a new tester in-house, and they needed help. So, an interview or two, and I transferred over there.
