PREFACE
The advances in the electronic, computer, and electromechanical tech-
nologies during the past decade have made possible a modern computer
industrial revolution capable of transporting men to the moon and back. The
use of computer electronics in business and the government here on earth has
resulted in increased production and efficiency in many industrial processes,
and in many related consumer areas including the communications, enter-
tainment, medical, education, construction, clothes, and food industries.
The result has also been to create many new jobs in the design, manufact-
uring and servicing of computers and automation equipment. Our challange
is both to improve the effectiveness of the computer technology as well as
the application of this technology as a tool for the further improvement of the
life and well being of all.
The aim in developing the Ed- Lab training equipment has been to provide
a unit which covers the broadest range of computer subjects including logic,
digital systems, conversion between analog and digital signals, data process-
ing, control amplifier applications, and computer circuitry. The result is
the Ed-Lab System which holds the interest of the student and teacher by
providing an almost limitless potential for learning and creating. We at CES
use this equipment in the actual design and test of new digital and computer
equipment and find the learning a continuing enjoyment.
A second aim was to provide a rugged and professional trainer capable
of continuous and reliable use in the classroom. Instrument leads and jacks
and sturdy panels and construction are used and there are no loose parts to
get damaged or lost. Use of this Experiment Manual does not require any
previous experience by either the student or the instructor. The material is
seperated into the following sub-sections: BASIC DIGITAL CONCEPTS, LOGIC
TECHNIQUES, ARITHMETIC TECHNIQUES, SEQUENTIAL SYSTEMS, BASIC
ANALOG CONCEPTS, CONVERSION TECHNIQUES, and COMPUTER CffiCUITS.
Experiments are self-contained and students are urged to tackle any experi-
ments and to proceed at their own rate. We know that you will devise many
new and interesting experiments and applications.
This manual has been written to convey the technical material that we
have found to be both most useful in the understanding and design of digital and
computer equipment , and most compatable with the educational curricula and
goals. The experiments are written in a practical fashion with all the necess-
ary descriptive material and exercises included. Experiments and exercises
are textbook compatable. The Computer Systems Lab. - Ed Lab 700 and this
manual will provide you with the knowledge and experience which we hope will
be invaluable in your future endeavors.

FIRST AID for ELECTRICAL SHOCK
If you observe an accident involving electrical shock,
DON'T JUST STAND THERE - DO SOMETHING I
RESCUE OF SHOCK VICTIM
The victim of electrical shock is dependent upon you to give him prompt first aid.
Observe these precautions:
1. Shut off the high voltage.
2. If the high voltage cannot be turned off without delay, free the victim from the
live conductor. REMEMBER:
a, Protect yourself with dry insulating material.
b. Use a dry board, your belt, dry clothing, or other non-conducting material to
free the victim. When possible PUSH - DO NOT PULL the victim free of
the high voltage source.
c. DO NOT touch the victim with your bare hands until the high voltage circuit
is broken.
FIRST AID
The two most likely results of electrical shock are: bodily injury from falling, and
cessation of breathing. While doctors and pulmotors are being sent for, DO THESE
THINGS:
1. Control bleeding by use of pressure or a tourniquet.
2. Begin IMMEDIATELY to use artificial respiration if the victim is not breathing
or is breathing poorly:
a. Turn the victim on his back.
b. Clean the mouth, nose, and throat. (If they appear clean, start artificial
respiration immediately. If foreign matter is present, wipe it away quickly
with a cloth or your fingers).
c. Place the victim's head in the "sword-swallowing"
position. (Place the head as far back as possible so
that the front of the neck is stretched).
d. Hold the lower jaw up. (Insert your thumb between the
victim's teeth at the midline -pull the lower jaw force-
fully outward so that the lower teeth are further forward
than the upper teeth. Hold the jaw in this position as
long as the victim is unconscious).
e. Close the victim's nose. (Compress the nose between
your thumb and forefinger).
f. Blow air into the victim's lungs. (Take a deep breath
and cover the victim's open mouth with your open
mouth, making the contact air-tight. Blow until the
chest rises. If the chest does not rise when you blow,
improve the position of the victim's air passageway,
and blow more forcefully. Blow forcefully into adults,
and gently into children.
g. Let air out of the victim's lungs. (After the chest rises, quickly separate lip
contact with the victim allowing him to exhale).
h. Repeat steps f. and g. at the rate of 12 to 20 times per minute. Continue
rhythmically without interruption until the victim starts breathing or is
pronounced dead. (A smooth rhythm is desirable, but split-second timing is
not essential).
DON'T JUST ST AND THERE - DO SOMETHING!
