Technology timelines often highlight milestones and recognizable products. A more careful reading also asks what such lists leave out, and what archives, collections and documented examples can add.
The spread of the personal computer was not a single moment: the sources describe a market taking shape during the 1970s and a gradual change in how people related to computing.
Computers can help document and manage collections while also becoming part of the heritage a museum chooses to preserve. This dual role changes the questions around context, documentation and preservation.
Popular memory often conflates the Internet with the Web. The available sources tell a different story: a network that incorporated email, file transfer, remote access, discussion groups and systems for organizing information.
The history of the personal computer cannot be reduced to a single machine or year. The sources place its consolidation in the 1970s and identify 1977 as a key moment, when Apple, Commodore and Tandy formed the so-called “1977 Trinity.” This overview explains what can be established about that shift and where the available evidence leaves questions open.
The Internet’s history did not begin with the Web. Academic connectivity, shared protocols and email laid the groundwork; in Spain, RedIRIS and the documented early IP connections show a gradual transition, not a single moment of arrival.
GNU/Linux shows how software can be a composition of projects, licences and distributions rather than a single piece. It also raises a preservation question: is keeping a program enough to make it usable again?
The Macintosh 128K arrived in 1984 with a graphical interface and a mouse. Its history also calls for a distinction between being first and bringing an idea to a broad audience.
A look at archives, museums, and projects that treat video games as material and digital culture: games, machines, documents, software, and the decisions that shape their public memory.
The Web made the Internet more visible, but it did not create it. Email and other network services already enabled communication and remote access before links and browsers brought the network to a wider audience.
A reading of the Internet before the web through ARPANET, email, remote access and file transfer: uses that turned a research network into a communications infrastructure.
Introduced by IBM in August 1981, the 5150 entered a personal-computer story that already had other protagonists. Its importance is better understood as a shift in scale and expectations than as an absolute point of origin.
