I still have an old supermarket-purchased slide rule from my days at school (I was schooled at the juncture between slide rules/log tables and pocket calculators). After reading Cliff Stoll's article (http://www.uvm.edu/~pdodds/files/papers/others/2006/stoll2006a.pdf) I treated myself to a Faber-Castell 2/83N and I have to agree that it is *beautiful*. On my desk at work I keep its miniature cousin, a 62/83N prominently displayed.

At the NY MOMA exhibit (sadly static) I saw dozens of people explaining to their kids how the boards updated with a clacka-clacka-clacka. I could see the nostlagia in their eyes.

My guess is that e.g. the "BER" is from numBER or novemBER or somesuch. I have no idea if the LINC computer was important enough to be immortalised here. However, no luck looking for quotations with e.g. octoBER LINC LOCK... etc.
Maybe a bit longer that you want, but the UNIX 6th Edition source code, as presented in John Lions' commentary book is excellent reading. Clean, functional code with some well-documented "wow" moments.
