What Is a Full Computer Tower?
Atanasoff-Berry Computer ( ABC computer for short) is the first electronic computer in the world. Designed by American scientist Atanasov in 1937, it is not programmable and is only designed to solve linear equations. It was successfully tested in 1942. Is a recognized computer pioneer, laying a solid foundation for the development of today's mainframe and minicomputer. Two other scientists, Mozili and Eckert, borrowed and developed his ideas to make the first digital electronic computer ENIAC. But ENIAC's design idea is actually derived from Atanasov's previous design: reusable memory, logic circuits, based on binary operation, and using capacitors as memory. This computer was recognized as one of the IEEE milestones in 1990.

Atanasov-Berry computer computing battle
- Atanasoff's "Atanasoff-Berry Computer" (ABC) model machine is right at the threshold of analog and digital calculations. After Babic designed differential and analytical machines, in the second half of the 19th century, some physicists began to develop simulation computing devices. In 1876, L. Kelvin, who discovered the second law of thermodynamics, and his brother developed a "tidal harmonic analyzer" that can calculate the Fourier coefficient. In 1887, American physicist Michelson, who rejected Ether with E. Morey, developed a more accurate analyzer. In 1930, American scientist and educator V Bush and others developed a differential analyzer. When using it to calculate a fire table, the speed was dozens of times faster than manual calculation. Starting with ABC, human computing has advanced from analog to digital. And "ENIAC" marks the official entry of computers into the digital age.
- On October 19, 1973, a district court in Minnesota, U.S.A., heard 135 trials and pronounced in public: "Mozili and Eckert did not invent the first computer, but just used the ideas in Atanasov's invention. It also ruled that the patents of Mozili and Eckert were invalid. The ENIAC patent was derived from the invention of John Atanasov. The reason is that Atanasov told Mozili his initial idea of a computer as early as 1941. No such appeal was filed. However, the University of Iowa, where Atanasov is located, has not applied for a patent for the ABC computer, and it is not the computer designers who litigated the case, but two computer companies, Honeywell and Sperry Rand.

Atanasov-Berry Computer Replica
- When the school converted the basement into a classroom, the original ABC computer was eventually dismantled and all parts (except a storage drum) were discarded. In 1997, a research team led by John Gustafson of Ames Labs (on the Iowa campus) spent $ 350,000 to build a working copy of the ABC computer. Copy of this ABC computer
