Author John Buck chronicles his quest to credit inventors behind technology, notably Stephen Carlsen, creator of TIFF. Despite initial anonymity, Buck’s persistence led him to Carlsen, who shaped the standard while at Aldus. Tragically, Carlsen passed away before full recognition could be achieved. Buck updated TIFF’s Wikipedia entry, giving Carlsen the acknowledgment he deserves: “created by Stephen Carlsen, an engineer at Aldus.”
Overview of diskettes includes types (8″, 5.25″, 3.5″, 3″), sectoring distinctions (hard/soft), and write protection features. Also covers index holes, examples from various systems, product lists from 3M and boeder, and links to documents, manuals, and external sources about floppy disk technology.

The earliest Amiga prototype, known as Lorraine and built from three sizable breadboard stacks, was displayed publicly at the Amiga 40 event in Germany. Maintained by original team member Dale Luck, it was shown in Germany for the first time, with event photos provided and published by Amiga user ‘Pittrock.’

The Internet has evolved through 7 phases:
Each phase builds on the last, transforming how we connect and interact with technology, ultimately leading to an intelligent and universally accessible digital landscape.

Joseph Weizenbaum created ELIZA in 1964, an early chatbot simulating therapy by reflecting users’ statements. Unexpectedly, users grew emotionally attached to ELIZA, projecting human traits onto it. Fast forward to 2022, OpenAI’s ChatGPT made AI accessible, rapidly gaining over 100 million users. Now, chatbots serve complex roles including romantic partners and therapists, prompting ethical considerations. The history of AI spans symbolic and statistical approaches, leading to today’s language models, which are statistical products of vast datasets rather than explicit rules. Metaphorical interfaces, such as the desktop metaphor for personal computers, enhance user understanding of technology. ChatGPT leverages conversation as its guiding metaphor, allowing intuitive interaction with AI.

Turbo Pascal 3.0-compatible compiler, PASTA/80, generates machine code for Z80 machines (ZX Spectrum, CP/M). It uses a single-pass recursive descent approach, focusing on speed over optimization. Supports most Turbo Pascal 3.0 features, including basic types, control structures, file I/O, and overlays (for larger programs). Built using Free Pascal and relies on sjasmplus for assembly. It can output various formats (binary, snapshot, tape) for CP/M and ZX Spectrum targets, with an IDE mode available. Licensed under GPL with a linking exception for binaries.
RFCs (Requests for Comments) are documents that establish internet standards and communication protocols, vital for technology and IT professionals. Originating in 1969, they record development ideas and standards, helping ensure consistent operation across the network. Key to the internet’s history, early networking efforts, including ARPANET, laid the groundwork. RFCs explain protocols like TCP/IP and DNS, serving as essential references for reliable system design. Understanding RFC terminology is crucial for accurate implementation. The RFC Editor and IETF maintain and publish these documents, which are foundational for internet architecture and ongoing technological evolution.

Cambridge University Library is working to recover valuable historical information trapped on old floppy disks, including items from Stephen Hawking’s archives. The “Future Nostalgia” project addresses challenges posed by legacy data storage, as many disks risk data loss due to degrading materials. Archivists face technical hurdles in accessing and translating content from various disk formats, as finding compatible hardware is increasingly difficult. The project aims to preserve these forgotten documents for future generations and involves public participation, inviting individuals to bring their own floppy disks for exploration.
