Hi. I have next problem. I must execute a lot of shell
scripts on low memory computer (4Mb). bash is very big for
this task and have unnecessery possibilities (readline, job
control etc). At this time i find only one simple shell
for scripts evaluating - ash. It have 50Kb text body.
I try find source code for bourne shell (not bourne again shell), but failed.

You won't find source code for the original sh, because it's copyrighted.
There might be a version for BSD, but I wouldn't know where to find that. If you can find the source code, it should be relatively easy to compile.
There is a collection of shells on sunsite, in the /pub/Linux/system/shells directory. You can look there for a small one.
From the LSM entry, rc seems to be pretty small.

You could try kiss (keep it simple shell). I believe it's in the same directory I mentioned before. It has a lot of builtin functions (this can save you from running some other binaries).
You can compile it without any command line editing, yielding a rather small binary. (I don't recall the exact size.)

kiss is good simple shell for resque disks, but it cannot
execute control construction;
for, while, if, etc...
