How to install the pseduo device driver?

Question

I downloaded one package to produce high resolution delay ( similar to sleep() ).
Here is the comment text in main file:
Written by Jon Zeeff umix!b-tech!zeeff
This "device driver" uses the kernel delay() call to allow calls
to nap() from user processes. Nap() is like sleep, but with finer
resolution.
Compile with cc -O -c ft.c
Written for a Sys V.3 system, but should work on others.
For Sys V.3:
Make a new kernel according to the instructions and then:
mknod /dev/ft c 28 0
modules/ft/config:
character(28)
prefix = ft
functions = open, close, read
Edit systems/system.std and add ft.
Copy ft.o to modules/ft/config
But, where is " modules " directory ? and where is system/system.std ??
thanks.
