ELECTROSIC SWITCHBOARD-MITAB, self-erasing blackboard
solves an efficiency problem for engineer Robert Machol, Grad., by
the simple twist of an ordinary telephone dial.
Electronic Brain Computes
Difficult Problems uIcdy
Inventors of MITAB (Mechani-
cal Transportation and Assign-
ment Blackboard) say this device
provides 20-minute answers to
problems larger electronic compu-
ters would take years to do the
"long way around."
MITAB was designed and built
by mathematicians and engineers
in the Operations Research group
of the University's Engineering
Research Institute for a bargain
price of $5,000.
It is described as a mechanical
blackboard that "erases itself" au-
tomatically but can restore the
problem as it was originally set up
if the operator wishes.
"Forgets" Instructions
Not a computer because it can-
not remember instructions, it can
only add, subtract and perform
other "simple" functions as finding
the best of two billion billion pos-
sible answers to a specific problem.
It was built by suggestion of
Merrill M. Flood, associate director
of ERI. James Munkres devised a
set of rules by which the machine
may solve a class of problems effi-
ciently and rapidly.
Actual construction was done by
engineers Bruce Weinert, Harold
Sherman .and Joseph Hoagbin,
mostly in their spare time, with
second hand equipment. Building
funds were supplied by the Engi-
neering Research Institute.
According to Robert Machol,
ERI systems engineer, the ma-{
chine has potential as a research
and instructional tool. Its solu-
tion methods can be adapted to
make conventional computers
even -more efficient.
MITAB has a great face con-
taining 400 indicators, 400 switch-
es and 800 lights. The indicators
are in twenty rows and columns,
solving a variety of combination-
permutation problems.
For instance, if 20 men had to do
20 jobs, and the rows represent
men and the columns, jobs; then
the machine can compute the
number of ways a business man-
ager can assign jobs (2,432,902,-
008,176,640,000). T h e problem
which the machine solves is finding
the best arrangement, using the
business manager's criteria-least
total cost and 'fastest operating
time.
Performs Tricks
It scan perform mathematical
tricks with its rows and columns,
solving problems in minutes that
a high speed computer would take
years to do.
However, if the high speed com-
puter is "shown the way" by MI-
TAB it could solve the problem in
seconds.

Underlying the border dispute
between the Central American
countries of Honduras and Nicara-
gua is a jungle-land area thought
to contain oil.
This natural resource caused
fighting this week and has resulted
in the two countries' going before
the Council of the Organization of
American States, even though the
land dispute has been simmering
for some time.
Both Nicaragua and Honduras
had claimed the area for many
years before 1906 when King Al-
phonso. XIII of Spain awarded it
to the latter.
Ruling Unrecognized
Nicaragua does not recognize
that arbitrary ruling, but claims
the Spanish king had no legal jur-
isdiction to award it to Honduras,
and claims the area as her own.
Some fighting has occurred dur-
ing the week but inadequate and
conflicting reports make the situa-
tion today unclear.
Both countries seem prepared to
accept arbitration before the OSA
now that it has established a five-
man investigating committee. This
group has been sent to the troubled
arera,
Both countries have charged
each other with aggression before
the OSA Council. Honduras sent
a note Tuesday claiming Nicara-
gua had invaded the territory
awarded her (Honduras) in 1906.
Honduras is reported to have be-
gun her move to expel Nicaraguans
from the disputed area Wednesday
by capturing the small town of
Mocoron. This prompted Nicaragua
to brand Honduras the aggressor.
Intervention Asked
Both nations have asked inter-
vontion under the Western Hemis-
phere's collective security pact. On
Friday, Honduras asked invocation
of the Rio Pact, which allows col-
lective a c t i o n and sanctions
against hemisphere aggressors.
.O*A's Council decided the Pact
should be invoked although this
requires a meeting of foreign min-
isters of member nations.
The five-man committee estab-
lished to investigate the trouble is
intended, in part, to provide a
"cooling off" period between the
states, a method which has been
used in the past.
The collectivei4 security pact
among the 21 American republics
is now in its 10th year. It was last
used to prevent war in 1954.
