This is likely the first example of remote access computing.The Z3, an early computer built by German engineer Konrad Zuse working in complete isolation from developments elsewhere, uses 2,300 relays, performs floating point binary arithmetic, and has a 22-bit word length.

The ABC was at the center of a patent dispute related to the invention of the computer, which was resolved in 1973 when it was shown that ENIAC co-designer John Mauchly had seen the ABC shortly after it became functional.
The legal result was a landmark: Atanasoff was declared the originator of several basic computer ideas, but the computer as a concept was declared un-patentable and thus freely open to all.
David Packard and Bill Hewlett found their company in a Palo Alto, California garage.
Their first product, the HP 200A Audio Oscillator, rapidly became a popular piece of test equipment for engineers.
The basic idea for bombes came from Polish code-breaker Marian Rejewski's 1938 "Bomba."After successfully demonstrating a proof-of-concept prototype in 1939, Professor John Vincent Atanasoff receives funds to build a full-scale machine at Iowa State College (now University).
The machine was designed and built by Atanasoff and graduate student Clifford Berry between 19.A total of ten Colossi were delivered, each using as many as 2,500 vacuum tubes.A series of pulleys transported continuous rolls of punched paper tape containing possible solutions to a particular code.A full-scale working replica of the ABC was completed in 1997, proving that the ABC machine functioned as Atanasoff had claimed.The replica is currently on display at the Computer History Museum.The result was the Relay Interpolator, later called the Bell Labs Model II.The Relay Interpolator used 440 relays, and since it was programmable by paper tape, was used for other applications following the war.The machine had a fifty-foot long camshaft running the length of machine that synchronized the machine’s thousands of component parts and used 3,500 relays.The Mark 1 produced mathematical tables but was soon superseded by electronic stored-program computers.The machine’s existence was not made public until the 1970s.Conceived by Harvard physics professor Howard Aiken, and designed and built by IBM, the Harvard Mark 1 is a room-sized, relay-based calculator.
