In
computer news this week:
The
only Chad I ever heard of was a singer in the 60's .... or - when you hear the
news explaining that a chad is related
to a punch card and you think that punch cards sound old fashioned - here's
just how old fashioned they are:

History of the Microcomputer Revolution - Part 1 -
In
the early 1800's a French inventor named Jacquard revolutionized the weaving
industry by creating a loom which could create extremely complicated designs by
reading instructions which were punched onto cards. The holes punched into the
cards - which were strung together into a chain of continuous instructions -
directed the loom which threads to use and what to do.
In
the mid 1800's a British inventor named Charles Babbage came up with the idea
of an Analytical Engine which would do mathematical computations using this
same concept of storing instructions onto cards, but he lacked the technology
to create the powerful engine needed.
A
contemporary of his, a woman named Augusta Ada Byron, who was the daughter of
the poet Lord Byron, was a gifted mathematician who immediately understood the
concepts and the possibilities of Babbage's analytical engine. She was able to
expand this concept into actual theoretical steps and procedures which would be
used in the computations, and she is credited by some as the first computer
programmer.
In
the late 1800's an American inventor named Herman Hollerith invented a
punchcard counting device which was used successfully for tabulating statistics
in taking the 1890 census. Hollerith's business eventually ran into financial
difficulties and he was forced to sell out to a company named CTR, which stood
for Computer Tabulating Recording.
A
young salesman at CTR named Tom Watson had started off his career selling
pianos off the back of a horse-drawn cart. Now Watson had worked his way up
through corporate America - spending time at the National Cash Register Company
along the way - and he recognized the potential of selling punchcard-based
calculating machines to American business. Watson would later take over this
company himself and in the 1920's rename it the International Business Machines
Corporation, IBM.
Modern
day mainframe computers as we know them were created by the United States
Military's need to calculate such things as shell trajectories in a minimal
amount of time. The electronic vacuum tube ENIAC computer, operational in 1945,
was a thousand times faster than the older electro-mechanical calculating
machines previously used for such tasks.
The ENIAC inventors went on to form the Univac corporation, a name which became
synonymous with computers, until the late 1950's when IBM fought back and
regained the industry with its IBM 360 mainframe.
.......
As
a historic note I'll point out that that these early mainframe computers used
batch processing, with programs inputted into them via punch cards.
And
now amazingly - almost unbelievably -
in the year 2000 we find the punch card system still in use in our election process; working obviously to some
degree, except of course, in Florida.
