Who paid for early AI computers, and who let outsiders use them?

"Er fuhr deshalb nach Hopferau und traf sich mit Zuse, um mit ihm einen Mietvertrag über die Nutzung des Rechners zu schließen."

"Herausragend war die noch in Relaistechnik ausgeführte Z11 , die der optischen Industrie, Universitäten und Flurbereinigungsbehörden verkauft wurde."

"Erste Tätigkeit war die Instandsetzung der 1945 von Konrad Zuse gebauten Z4 und deren Verleih bzw. Vermietung an die Eidgenössische Technische Hochschule Zürich ."

"Die Z4 diente der ETH Zürich zwischen 1950 und 1955 als zentraler Rechner."

"Banken waren nur gegen hohe Zinsen bereit, Kredite für das ihnen unbekannte Computergeschäft zu geben, eine staatliche Forschungsförderung gab es noch nicht"

"Insgesamt wurden an der Z4 von 1950 bis 1955 rund 100 Aufträge ausgeführt, darunter Raketenflugbahnberechnungen für die Maschinenfabrik Oerlikon-Bührle, Flugzeugberechnungen für die Eidgenössischen Flugzeugwerke in Emmen und für die Flug- und Fahrzeugwerke Altenrhein."

"Mit der Z5 berechnete Leitz Objektive."

"Auf der Basis der in Relaistechnik realisierten Z4 wurden die Zuse Z5 und die Zuse Z11 entwickelt, die an die optische Industrie sowie an Universitäten verkauft wurden."

"Nachdem der Mietvertrag der Z4 zwischen der ETH Zürich und Zuse 1955 abgelaufen war, verkaufte Zuse den Rechner im selben Jahr an das französische Rüstungsforschungsinstitut ISL ."

"Die Vermittlung zwischen Zuses Firma und dem auftraggebenden Reichsluftfahrtministerium lief über Joseph Jennissen (1905–1977), [ 5 ] und über Herbert Wagner ."

"In 1958, the DOD launched the Advanced Research Projects Agency (ARPA) with the goal of helping the United States avoid further technological surprises."

"Historians have attributed to DARPA a role in a number of high-profile inventions, such as the Internet (Newman 2002), the personal computer (Allan 2001)"

"the agency has grown to maintain an annual budget of $3 billion for extramural research funding overseen by roughly 100 program managers (Gallo 2018)."

"The National Science Foundation's ( NSF's ) investment in the nation's computational infrastructure began in a small way back in the 1960s, when NSF funded a number of campus computing centers."

"The first commercially available supercomputer, the Cray-1, went into production in 1977 at the NSF-supported National Center for Atmospheric Research (NSF NCAR)."

"NSFNET, launched in 1986 by NSF to connect academic researchers to a new system of supercomputer centers, became the backbone of the early internet."

"Throughout the 1980s and 1990s, NSF programs like Supercomputer Centers and the Partnership for Advanced Computational Infrastructure provided researchers nationwide with supercomputing resources to perform ever-more-advanced research and technological innovation."

"The Stampede supercomputer, located at the University of Texas at Austin's Texas Advanced Computing Center, has enabled research teams to predict where and when earthquakes may strike, how much sea levels could rise and how fast brain tumors grow."

"Simulations on the Blue Waters supercomputer at the University of Illinois National Center for Supercomputing Applications enabled researchers to capture the first image of a black hole in 2019, reshaping the understanding of these cosmic giants."

"The NSF Supercomputer Centers Program, in operation from 1985 to 1999, established the U.S. as a world leader in computational science. These centers expanded access to state-of-the-art supercomputer resources from only two universities in the early 1980s to over 200 universities by the early 1990s."

"The 1986 creation of NSFNET, a network that connected researchers to the supercomputer centers. NSFNET served as the internet's backbone until its commercialization in the mid-1990s and led directly to today's internet."

"The U.S. National Science Foundation supports the development and provides access to state-of-the-art supercomputer hardware, software and infrastructure, driving transformative discoveries and innovation."

"In November 2025, NSF began installing Horizon , the nation's fastest academic supercomputer. Horizon's simulation speed will provide unprecedented computing and AI capabilities."

"This includes NSF grantees, re- searchers supported by other Federal agencies (non-classified), industrial researchers, and un- supported researchers."

"They are the focal points for the development of a national research network linking re- searchers at over 20~ universities and institu- tions to the supercomputers and to each other."

"These supercomputers are strategic components of the nation's defensive capabilities, drive innovation through open access to the scientific community, and are the basis upon which to build safe and trustworthy AI capability for the nation."

"Through the Exascale Computing Project, DOE worked with industry partners to co-design and develop critical components of the computer chips that power today's leading AI models and partnered with leading academic institutions to develop scalable high-performance software libraries."

"How can DOE improve awareness of existing allocation processes for DOE's AI-capable supercomputers and AI testbeds for smaller companies and newer research teams?"
