370, the exams for that course were just a blast, only exams I've had genuine fun taking in my life. Would have done 470 but I graduated a semester early (that and programming languages courses are ones I retrospectively regret not having taken). Computer Organization and Design 4ed was the one at the time I think - it is Hennessy.

I love computer science now a lot more than I did at the time, heh, but that's part of why I bothered finishing early. The professional environment suits me well.

Just curious, what kind of work do you do now?

Software engineer. Same username on github will lead you to linkedin if you're curious about my (relatively short) career timeline there.
