Early Logic Machines

Early Machines Devised to Solve Problems in logical system The worlds scratch real logic machine, in the sense that it could actually be officed to clobber full-dress logic problems, was invented in the earlier 1800s by the British scientist and statesman Charles Stanhope (third Earl of Stanhope). A man of some talents, the Earl designed a guile called the Stanhope Demonstrator, which was a small box with a window in the top, along with two antithetical colored slides that the user pushed into slots in the sides.

In accompaniment it wasnt until somewhat sixty years after his death that the Earls notes and one of his devices send packing into the hands of the Reverend Robert Harley, who later on published an clause on the Stanhope Demonstrator in 1879. Working on a somewhat diff erent approach was the British logician and economic expert William Stanley Jevons, who, in 1869, produced the earliest model of his famous Jevons logic Machine. The Jevons Logic Machine was notable because it was the first machine that could solve a logical problem faster than that problem could be resolved without using the machine!

Jevons was an aficionado of Boolean logic, and his solution was something of a brood between a logical abacus and a cushy (in fact it was sometimes referred to as a Logic pianissimo). This device, which was about 3 feet tall, consisted of keys, levers, and pulleys, along with garn er that could be all apparent or hidden. W! hen the operator pressed keys representing logical operations, the discriminate letters appeared to reveal the result.
