Those two chips come after the tone generator.
They take the square wave outputs of the TG (16,8,4,2) and buffer them and also provide the quasi triangle wave (by attenuating the higher foots more).
This gives four outputs. Two for each DCO. One is square the other triangle for each DCO.

IC4 and IC5 they come right before the MSM5232 chip and inputs at
the MSM5232 are marked as 16", 8", 4" and 2", looks like they are the
clock dividers.
I don't think so. The octave selection is done inside the MSM5232 tone generator.
Which chip are you talking about?

I'm not sure, but looks like they are the clock dividers for the octave switches.
Yes, looks more like it. Interesting stuff, what does that Pin 1 do then?
