From page 6, describing the representation of binary numbers: <i>The word bigit is defined as binary digit.</i><p>I'm kind of sad that "bigit" didn't stick.<p>Edit:<p>From page 291, I'm also enjoying:<p><i>The "turn-on" and "turn-off" procedures for the computer naturally seem to be more in the domain of the engineers rather than that of the programmers; however, the turn-off procedure has been simplified to the extent that the programmers can do it.</i><p>The machine has two different breakpoints types-- "red" and "green". That's an interesting feature. The instruction set architectures I'm used to don't have such a concept and it's interesting to think about.
