The Atanasoff-Berry Computer Replica

it's hard to imagine what life would be like without computers in the past 57 years the computer has grown from a curiosity to an everyday machine that helps us in our work education and recreational activities and while computers have become commonplace and in many ways irreplaceable most people do not know who invented this wondrous machine many would be amazed to know it was a professor at Iowa State University John Vincent Anna Nassif had a problem his students were taking weeks to mechanically calculate the linear equations used in their physics courses he knew there had to be a faster way so in 1934 Atanasoff began to explore some of the principles that he would later use in the new computing device from 1939 to 1940 - with the help of graduate student Clifford berry he designed and built the first electronic digital computer the ABC the Adhan Asaf very computer working in the basement of Iowa State's physics building add an ass off and Barry assembled a stunning array of advances that together form the foundation of modern computing among them are a binary system of arithmetic separate memory and computing functions electronic amplifiers as on-off switches and electronic circuits for logical addition and subtraction World War two interrupted the work of a Denese often bury a dannis off left Iowa State to work for the US Navy his invention was never patented the original ABC was disassembled scavenged for parts after the war later computing machines dwarfed the ABC in size and stature it was not until a 1973 court case over the patent of one of those later computers the ENIAC that add an ass off was recognized for his work although opposing lawyers argue that the ABC was never completed that it did not work still a federal judge voided the ENIAC patent and ruled that the basic ideas of modern computing came from one dr. John Vincent at a NASA public acceptance however has been slow so to prove that a Dan Asaph's machine did in fact work a team of Iowa State University in Ames Laboratory scientists faculty and students built an authentic full-size working replica of the ABC building the replica required considerable time and patience as the team retraced the steps taken by a Danis often Barry because the original computer no longer existed the replica team relied on some of Atanasoff original papers grainy photographs and the fading memories of those who took part in the original project the team's goal was to produce a replica that would be as true to the original as possible it required painstaking care and using vintage electronic parts such as 1940s vacuum tubes brushes and card punches prevalent in the era but hard to find today it took nearly three years but they succeeded thanks to the support of alumni and Friends of Iowa State University and the add a NASA family and the Machine does just what it was designed to do compute electronically the reconstruction of something like this is such great history to reach back 57 years and and see how far we have come is is amazing and it's also it feels like we're doing something that's intellectually very right to give credit to these these men these pioneers that really started the whole thing John Atanasoff did not live to see his computer rebuilt he died in 1995 but the replica honors his achievement and all those before and after him who gave us the computer age since the beginning many men have worked on computing and many have furnished elements that were important this applies to luckily excerpt some members of staff such as works greater than others in a larger sense no man invents anything he builds an extensive little with his friends and on the shoulders of others you
