CPU Shack Museum is an online museum documenting the history of microprocessors, with a collection of over 20,000 CPUs from more than 150 manufacturers plus a large EPROM collection. The site features detailed articles on individual chips, manufacturers, and processor history, along with reference guides, photos, and test boards. It functions as a hobbyist-run archive and blog covering both mainstream and obscure processors.

Antique Chip Collector's Page is a personal website run by a hobbyist collector focused on vintage integrated circuits and microprocessors from the 1960s-80s, including well-known chips like the Intel 4004, MOS 6502, and Motorola 6800. It offers guidance for identifying and dating chips, information on manufacturers, and advice for new and advanced collectors, along with the creator's own chip-based artwork. The site also includes a blog documenting collecting news and media coverage.

A private personal collection of Carl Friend's, covering calculating devices from slide rules to microcomputers and workstations, with a particular focus on minicomputers. The site offers a museum catalogue, narrative descriptions, a reference shelf, a wish list, and links to related resources.

Old Computer Hut, a personal collection of vintage British and international computers with photographs and descriptions.

VaxArchive is a hobbyist website providing detailed technical documentation on Digital Equipment Corporation's VAX systems, including VAXstation 2000/3100 pages, Q-bus and Unibus module field guides, disk and tape controller documentation, cabling guides, and VMS version compatibility information. It functions as a reference collection of manuals, FAQs, and hardware identification guides rather than a formal archive or institution.

SimH is an open-source project providing highly portable simulators for historically significant computer systems, including DEC PDP and VAX machines, IBM systems, Data General, HP, Honeywell, and others. Maintained primarily by Bob Supnik with contributions from others such as J. David Bryan, the site offers downloadable simulator source code, documentation, software kits, and papers on the history of computing and simulation. It represents a long-running individual/volunteer effort rather than an institutional archive.

Dusty Decks is Paul McJones's personal research site preserving historic software and documenting the history of programming languages and software engineering, including detailed accounts of projects like APL at Berkeley's Management Science Laboratory, Peter Naur's ALGOL 60 papers, and LISP pioneers. It compiles primary sources, scanned documents, interviews, and firsthand recollections, with links to archives such as the Danish Data History Association and the Computer History Museum.

Mark Smotherman's detailed historical account of the S-1 supercomputer project (1975-1988), led by Lowell Wood at Lawrence Livermore National Lab and largely designed by Stanford graduate students Tom McWilliams and Curt Widdoes. The site documents the project's multiple processor generations (Mark I, Mark IIA, and the AAP), its technical innovations such as branch prediction and cache coherency, and its influence on CAD tools and programming languages like Common LISP and gcc. It includes photographs, technical specifications, and design details drawn from project documents and personal research.

Workbench Nostalgia is Greg Donner's personal website documenting the version history of AmigaOS's Workbench graphical user interface, from its first release through later beta and licensed variants. It provides a detailed OS version table with screenshots, credits, and notes on disk preservation, along with pointers to emulation and hardware sources for the Amiga community. The site invites contributions such as recollections, screenshots, and undocumented features from fellow enthusiasts.

Susan Sherwood's personal compendium of programming languages, hosted on her University of York user pages, presenting an alphabetical, informal catalogue of languages with historical notes, quotations, and code fragments. It is explicitly described as a personal, incomplete list of languages the author has encountered, rather than a formal academic or institutional resource.
