Just over a year ago I got my Unicomp Model M Mini, a newly manufactured version of what is in my estimation the best computer keyboard ever, the IBM Model M SSK. The Minis and the SSKs are like a regular IBM Model M, but they don’t have a number pad at the right, so I can put the trackball there and not have to reach for it.
In my elementary school, we weren’t given grades of A B C D F as was the standard before and since. Instead, New Haven R-II school employed a different set of letters that meant the same thing. They were E S M I F. I have no idea how this came to pass, but I hope it was because some person seeking a doctorate in education realized that his dissertation was due tomorrow and he had nothing. Frankly, I could get behind that kind of education theory. Beats modern pedagogy, anyway.
