The 1929 desk in this image isn't too far from a physical instantiation of Vannevar Bush's Memex which didn't appear until 1939 (1945 published).

The earliest time of composition of any of these fragmentswas, so far as we can judge, 1929. The date at which the latestdatable fragment was written was August 1948. By far thegreatest number came from typescripts which were dictated from1945- 1948
Based on the dating provided by Anscombe and von Wright, Wittgenstein's zettelkasten slips dated from 1929 to 1948.
for reference LW's dates were 1889-1951
Supposing that the notes preceded the typescripts and not the other way around as Anscombe and von Wright indicate, the majority of the notes were turned into written work (typescripts) which were dictated from 1945-1948.
What was LW's process? Note taking, arranging/outlining, and then dictation followed by editing? Dictating would have been easier/faster certainly if he'd already written down his cards and could simply read from them to a secretary.
