Ah. Yes, OK, I sympathize with this sentiment but also feel it’s something of a lost cause for mass-produced keyboards. As far as Ctrl moving from one position to another, from what I can find it’s more that the two options coexisted for while, and eventually the current (and arguably worse) one outcompeted the other.

Specifically:

- The ADM-3A[1] (mid ’70s) had Ctrl above Shift and apparently no Caps Lock.

- The Lisp machines[2,3] (late ’70s to mid ’80s) had Ctrl below Shift and Rub Out above Shift.

- The IBM 3270 series (from the early ’70s onwards) terminals (those that were capable of lower-case input) are pictured in Wikipedia[4] with a Caps Lock above Shift and no Ctrl (which agrees with their input model) but I get the impression that IBM produced a bajillion keyboard variations for these.

- The Model F variants for the XT and the AT (first half of the ’80s) has Ctrl above left Shift, Alt below it, and Caps Lock below right Shift[5], as well as 5×2 function keys on the left and no separate arrow keys; the later Model M variants (1985 onwards) use the modern layout; yet once again, looking at the separate pages for the Model F and the Model M, I get the impression that IBM simply produced a bajillion different versions of them.

- The ANSI standard to which the appellation of “ANSI layout” refers is ANSI X3.154-1988, so presumably things had settled by then?..
