I removed some material about loading the instruction register during the Fetch phase (because we don't reference the phases anywhere else in this article) and some (to me) irrelevent details about Memory Address Register (MAR) and Memoery Data Register (MDR).

Needs a reference.

Other developments of IR and related terms

Extremely disappointing article. Nothing about arrays of IRs and various other extensions. Perhaps more serious that there's no consideration of the microcode. Actually, my own architectural knowledge is sufficiently dated that I'm not even sure microcode is as important as it used to be, but if it's been replaced, then that should also be mentioned in this article. I really can't decide if this article is even worth citing in my course... Maybe it's just historical trivia now, but in that case the superseding concepts should be made more clear.

Indeed. The references in the article are from about 25 years ago. On the other hand, when people innocently ask me how computers work, internally, I describe the PDP-8 which is from over 50 years ago, because its architecture is simple enough that even the technically inept can gain some sort of understanding.
