Kiev 6S or 6C TTL important question

I am about to purchase this:

Kiev 6S TTL from 1982.
Does the focusing screen offer a split rangefinder or only a microprism?

If not, is it possible to swap the screen from the Kiev 60? (in order to have a split rangefinder).

Thank You in advance.

Hi Tom,
alas , only microprisms as I can see on mine.
So , it seem easy to remove it and change for a better (modern) accurate glass.
