The T2A font encoding is one of the supported ways to associate characters (such as "letter ы") to slots in a TeX font table.  In particular, an encoding determines a character set which may — as with T2A — or may not (T1) include Cyrillic.

Same thing but for plain text files.  It defines which bit sequences stand for which characters.

What I use is surely outdated, since I have been using it for more years than I care to remember---ever since I started doing translation of math papers for the AMS, which was a long time ago. What I do to typeset in Russian is, follow the indications given for the \cyracc AMS family: one uses the {\cyr ...} environment and, within it, one uses the standard Russian transliteration, except for things like p1 for the soft sign, and p2 for the hard sign, which are not obvious.

Here is a minimal example in LaTeX — yours was in plain TeX, to which it ought to be adaptable, but I am not sure how.  Success depends on the presence of all the appropriate files for the cmr font family, but this should be automatic on most of this century installations.

%%%%%%%%%%%%%%
\documentclass{amsart}
%%%%%%%%%%
% in the preamble, add the following incantations:
%%%%%%%%%%
\usepackage[utf8]{inputenc}
% make sure that in TeXShop preferences (source/input panel), Unicode (UTF8) encoding is selected.
\usepackage[T1,T2A]{fontenc} % whichever encoding is mentioned first, is the "default"
\def\cyr{\fontencoding{T2A}\fontfamily{cmr}\selectfont}
%%%%%%%%%%
\begin{document}
{\cyr Как бы {\bfseries цыплята} нас по осени {\itshape не {\bfseries посчитали}}.}\par
You don't have to use the ø-less T2A if you don't want to.
\end{document}
%%%%%%%%%%%%%%%

Here is what I get:

> Thank your for your comment about что касается упражнения, you are absolutely right, my fault. Only I need to make a small correction to your Grammar comment: after the verb касатъся, one uses Genitive, not Accusative (which I should have done, but didn't). The Accusative for упражнение is still упражнение (as a neuter noun).

I stand corrected.  Genitive is right.  Don't know what I was thinking.

as ever,
