Ancient Web: The Intel 4004 Site Argues the History From the Inside

The Intel 4004 has been called the first commercial microprocessor so often that the sentence can become wallpaper. Intel4004.com is more interesting because it gets into the messy part: who conceived it, who actually built it, and which manufacturing breakthroughs made the chip possible.

Visit the Intel 4004 history site

The site is built around Federico Faggin’s account of the project. Faggin joined Intel from Fairchild in April 1970 and led the implementation of the MCS-4 chip set for Busicom. His pages separate the earlier architectural proposal by Ted Hoff and Stan Mazor from the later design and development work that turned the idea into working silicon.

That distinction is the point of the site. It is not a neutral museum label. It is a technical participant arguing the historical record.

The manufacturing story matters

A large part of the material deals with silicon-gate technology, self-aligned gates, buried contacts, chip layout, and the practical problem of putting roughly 2,300 transistors into one commercially manufacturable processor in 1971.

That makes the site unusually useful. Plenty of histories say the 4004 “changed computing.” Fewer explain why the available MOS process technology was such a constraint or why Faggin’s background at Fairchild mattered to getting the design onto a chip.

The archive also includes papers, patent references, interviews, photographs, and detailed responses to accounts that Faggin believes overstate the role of others. Even if a researcher ultimately consults multiple histories, this is exactly the kind of primary-source perspective worth preserving.

For webmasters, the site is also a reminder that a narrow technical subject can support years of useful material without needing a giant publishing platform. One disputed detail leads to a patent. The patent leads to a process history. The process history leads to the entire early microprocessor industry.

The 4004 is famous. The argument over how it actually became silicon is less tidy, and therefore much more interesting.

Ancient Web: CPU-GALAXY Is a Private Museum of Rare Chips

CPU-GALAXY is an online museum where every processor, board and strange ceramic chip pictured on the site comes from the owner’s actual collection. This is not a generated catalog. Peter has the stuff.

Visit CPU-GALAXY

The site describes itself as a virtual museum of vintage and rare CPUs, chips, boards and related hardware. Exhibits combine high-resolution photographs with descriptions and datasheets, turning what could have been a photo gallery into a useful identification and research resource.

Peter’s “about” page explains the motivation plainly: save old chips, photograph them properly, share the collection, and pass on handling knowledge to newer collectors.

That last part matters more than it sounds.

Rare silicon is easy to destroy

Chip collecting has its own physical problems. Pins bend. Packages get dirty. Collectors want to expose dies. Old boards get scrapped. Parts that look like worthless ceramic rectangles can be historically significant.

Peter writes that experienced collectors learned cleaning, pin straightening and die work through trial and error, sometimes killing rare devices in the process. The tutorials exist partly so somebody else does not have to repeat all of those mistakes.

His best collecting story is pure CacheRat material: an early Intel 8008 processor board found in the garbage.

The site treats old electronics as artifacts rather than generic e-waste. An Intel 4004, 8008, early EPROM, DEC processor or IBM module is not valuable only because collectors will pay for it. It is evidence of how computing was physically built.

A museum without waiting for a building

Private collections disappear easily. Hardware gets sold in lots, estates get cleared, labels separate from objects, and a carefully accumulated collection becomes fifty unrelated auction listings.

Photographing and documenting the collection creates a second layer of preservation. Even if ownership changes later, there is still a searchable record connecting part numbers, package styles, boards and datasheets.

For webmasters, CPU-GALAXY is another good example of a site whose SEO comes almost accidentally from exactness. Processor numbers and obscure chip markings are precisely the things researchers type into search boxes.

CPU-GALAXY was pulled from CacheRat’s larger list of old and specialist sites.

If you have ever picked up an unidentified processor and typed every marking into a search engine, this museum is built for you.
