• Shustek is especially proud of the pieces in the collection that were rescued from junk heaps, like the Johnniac.
• In 1954 he joined RAND Corporation where he developed utility software for the JOHNNIAC computer and worked on SAGE computer.
• In 1954, Martin Davis programmed Presburger's algorithm for a JOHNNIAC vacuum tube computer at the Princeton Institute for Advanced Study.
• Next to the Johnniac is a large chunk of an IBM . SAGE built in the 1950s as part of an early warning air-defense system.
• It was at RAND that he began the JOHNNIAC project, named after John von Neumann, and based on the IAS machine and selectron tube memory.
• Like the IAS machine, JOHNNIAC used 40-bit words, and included 1024 words of Selectron tube main memory, each holding 256 bits of data.
• The CYCLONE at Iowa State University was a direct clone of JOHNNIAC, and was instruction compatible with it ( the ILLIAC I may have been as well ).
• Shuman developed his mathematical models on one of the world's first computers, the JOHNNIAC . He also attended classes taught by J . Robert Oppenheimer and Albert Einstein.
• Now the one-of-a-kind Johnniac, named for the computer pioneer John von Neumann, is safely ensconced 350 miles north, at the Computer Museum History Center here.
• A skilled hands-on engineer, Uncapher had a reputation for being the only one able to make RAND's Johnniac, an early computer named for John von Neumann, work reliably.
• While they were more reliable and faster than the Williams tube, that cost and the lack of availability, meant they were used only in one computer : the RAND Corporation's JOHNNIAC.
• The Johnniac is part of a vast collection of computer and electronic equipment assembled over the last two decades by a dedicated cadre of computer pioneers who are determined to prevent the industry's tangible roots from slipping away.
• Also running on a JOHNNIAC, the Logic Theory Machine constructed proofs from a small set of propositional axioms and three deduction rules : modus ponens, ( propositional ) variable substitution, and the replacement of formulas by their definition.
• In the 1950s, modified standard versions of the A, B, and C models were used as console typewriters or terminals on many early computers ( e . g ., JOHNNIAC, IBM 1620, PDP-1 ).
• He was a major force in the design and construction of early computing machinery, including the IAS machine, and subsequently directed the construction of JOHNNIAC . His publication of EDUNET in 1967 presaged the details and rise of the early internet.
• Twelve years ago, Keith Uncapher, a computer scientist at the RAND Corp ., was shocked to discover that the Johnniac, a behemoth of a computer he had helped develop in the 1950s, had been left to rust in a parking lot behind the Museum of Science and Industry in Los Angeles.
• The museum is also the repository for unique machines like the Johnniac and the WISC, or Wisconsin Integrally Synchronized Computer, a mainframe computer built by Gene Amdahl for his doctoral dissertation at the University of Wisconsin in 1953 . ( Amdahl designed early mainframes at IBM and later founded the Amdahl Corp ., which was a major computer manufacturer . ) The WISC was discovered in Wisconsin in an engineer's basement, where it had apparently been used on occasion for target practice.
