The IBM 1401 restoration website documents two working 1960s mainframes with manuals, repair notes, oral histories, schematics, photographs, software, and years of volunteer work. It feels less like a homepage than a machine room rendered in HTML.
The MOnSter 6502 project recreates the classic MOS 6502 processor at transistor scale on a 12-by-15-inch circuit board with thousands of visible components. It turns an integrated circuit back into something you can point at.
Jason Scott started TEXTFILES.COM in 1998 to preserve BBS-era text files he had collected in his youth. The project grew into a huge archive of computer culture built around a simple idea: copies survive.
Steve's Old Computer Museum presents around 150 vintage computers with photographs, specifications, prices, advertisements, and short histories. The collection captures how wildly different personal computers looked before beige boxes won the argument.
Herb Johnson's Retrotechnology site documents the repair, restoration, history, and reuse of 1970s and 1980s computers, with deep material on S-100 systems, Digital Research, CP/M, and vintage hardware.
A humor page last modified in 2001 preserves engineer jokes, Unix-era one-liners, a Windows NT error message, BBS material and broken BOFH links as a tiny fossil of technical culture.
Michelle A. Hoyle's hand-built History of Computing Science, developed from the 1990s into the 2000s, became a durable educational reference cited by courses, books and later computing-history pages.
