To run different programmes required changing the directions
that these cables were connected to the relays, as well of
course as using a different set of holed cards.
Mathematical answers were displayed upon walls lined with common
light globes that took an army of technicians to de-code to
anything that bordered human understanding.
Blown globes, burnt out relays and power supply problems often
played havoc with the work being generated by these oversized
pocket calculators.
A far cry from using a keyboard and monitor, the interfaces that
you see before you.
(The earliest of the transistorised personal computers, during
the 1970's, still did not have a keyboard or monitor screen but
a series of switches and LED lights to display answers.)
Still, these monuments to electrical engineering were able to
calculate where a cannon shell would land if an artillery piece
were aimed at certain angles, and were responsible for cracking
vital intelligence codes transmitted by military foes.
One of the listings of famous understatements of history was
that the world demand for computer technology would run out to
less than ten units.
The Modern Computer
───────────────────
The modern CPU is the end result of transistor technology.
Transistors are basically devices that do not conduct
electricity perfectly, and this imperfection was found to have
ability in manipulating electrical current.
In the same way that the old thermionic valves of the early
radios and television sets were able to be used to amplify a
signal, the transistor can, using a number of different current
and signal inputs, amplify, regulate, switch and divert current.
