Sophie’s Cabinet of Computing Curiosities


Field guides to the hardware, standards and historical accidents that make computers work

Wide, dark purple and sepia illustration of Sophie’s Cabinet of Computing Curiosities, imagined as an old wooden museum cabinet filled with the strange physical history of computing. Open drawers contain tangled vintage connectors and cables, punched cards and paper tape, an audio cassette, Sinclair Microdrive, exposed hard disk, fibre-optic strands, circuit boards, expansion cards and a modern NVMe solid-state drive. Other closed drawers are labelled with broader and more mysterious categories, suggesting obsolete technologies, proprietary mysteries and future antiques still waiting to be discovered. Alongside the cabinet are a purple desk lamp, technical books, magnifying glass and small eccentric ornaments, giving the scene the atmosphere of a Victorian collector’s study crossed with a computer laboratory. The image deliberately leaves several drawers unopened, implying that Sophie’s collection of technological curiosities can continue to expand. Any resemblance between the bald figure wearing a purple scarf and Sir Uncle Clive Sinclair is suspiciously intentional and it is his proximity to the Microdrive that is, naturally, entirely coincidental.

Welcome to Sophie’s Cabinet of Computing Curiosities!

An accidentally created collection of field guides to the technologies, standards, forgotten contraptions and occasionally magnificent mistakes hiding beneath modern computing. They form a logical group; so voilà!

Here live the things that connect, remember and communicate: cables designed by optimists, storage formats that were definitely the future, interfaces requiring ritual termination, and standards whose designers apparently assumed nobody would ever need to understand them thirty years later.

Part technical history, part taxonomy, part technological archaeology, the Cabinet looks beyond what something does to ask how it works, why anyone thought it was a good idea, what went wrong, and why some supposedly obsolete ideas stubbornly refuse to die.

Go ahead – open a drawer. There is almost certainly something peculiar inside.

Sophie’s Great Cable Menagerie96 connector families assessed; 5 scored dimensions; 40% weight given to tangles; -25 maximum snag penalty
Sophie’s Encyclopaedia of Things That RememberFrom 80-column punched cards to 245.76 TB SSDs; Why the 2.88 MB floppy refuses to die; splendidly improbable ways of remembering bits; your 1 TB disk is only 0.91 TiB; BBC Domesday lesson.
Sophie’s Compendium of Things That Talk71 interface/bus/network families, security implications, debugging lessons, thin Ethernet and its splendid ability to turn moving one desk into an office-wide event, serial-vs-parallel physics, USB/FireWire/Thunderbolt, embedded buses, coherent fabrics, chiplets, and the terabit future.
Sophie’s Gazetteer of Things That Know Where Your Bits AreStarts with CP/M, 8.3 filenames and the great / versus \ schism, then wanders through FAT and VFAT, HPFS, NTFS, Unix inodes, ext, Btrfs, ZFS, APFS, Unicode, optical filesystems, forensic recovery, pathname security, object stores and content-addressed storage.
Sophie’s Grammar of Things That Know What Your Data MeansWhat your bytes actually mean: the grammar that turns numbers into documents, pictures, databases, and other people’s problems.
Extensions are gossip; signatures are evidence: identifying files whose names may be optimistic, misleading, or outright lies.
Plain text’s surprisingly complicated life: Unicode, invisible characters, line endings, and CSV’s international disagreement about commas.
Documents with concealed passages: WordPerfect’s Reveal Codes, Word’s miniature filesystems, and Fast Save’s forensic compost heap.
Standards wars and patent tantrums: ODF versus OOXML, GIF’s licensing troubles, and why “open” needs several supplementary questions.
Pictures that compute, fonts that censor: executable PostScript, ever-decreasing cats, and Scunthorpe Sans behaving exactly as advertised.
Containers within containers: archives, software packages, executables, and the many layers hiding behind one innocent icon.
Small files with enormous ambitions: parser exploits, archive traversal, and Sophie’s Evil Signature™ decompression bomb.
Preserving meaning, not merely bytes: obsolete formats, emulator snapshots, original evidence, and helping the future understand what on Earth we saved.
Sophie’s Codex of Codecs, Containers, Copyrights, Confusion, and CompressionAwful Aural & Vibrant Video
A practical guide to understanding audio and video files: containers, codecs, compression, metadata, compatibility, and why technically valid files may still refuse to play. It also covers transcoding, legacy formats, legal and licensing complications, diagnosis, rescue, and long-term preservation.
