Some old-computer sites preserve photographs. The IBM 1401 Demo Lab and Restoration Project site preserves enough material to make you wonder whether the mainframe is slowly being backed up into HTML.
Visit the IBM 1401 restoration site
The project centers on two operational IBM 1401 systems at the Computer History Museum: one built in 1964 and brought from Hamm, Germany, and another built in 1961 from Darien, Connecticut.
The IBM 1401 was introduced in 1959 and became one of the defining business computers of the 1960s. IBM says that by the middle of the decade the 1401 family accounted for more than half of the world’s computers. It helped move businesses away from rooms full of specialized electromechanical card equipment toward stored-program computing.
That history is impressive. The website is impressive for a different reason: it shows the maintenance work.
Documentation all the way down
The site contains restoration status reports, component notes, manuals, Automated Logic Diagrams, maintenance procedures, photographs, software, bug logs, oral-history material, scanned IBM documents, card-reader information, printer work, tape-drive work and stories from the people who knew the machines when they were ordinary equipment instead of museum pieces.
A 2007 status report recorded roughly 9,000 volunteer hours by that point. The restoration team included retired IBM customer engineers and other volunteers who could still recognize what a half-century-old machine was trying to tell them when it stopped behaving.
The archive kept growing after the initial restoration. Its update pages show new manuals, technical notes and historical material appearing years later.
This is the part of preservation that gets missed when people think archiving means taking a photograph and putting an object behind glass. A working computer is a system of procedures, maintenance knowledge, software, peripherals, sounds, habits and people.
The website looks like the workbench
The main page is enormous. It is dense with links. Some sections have been added across years by different hands. There are smileys, odd spacing, old-school navigation and more technical material than any modern redesign consultant would allow onto one page without staging an intervention.
Good.
For researchers, that density is the value. For webmasters, it demonstrates something worth stealing: the site’s priority is keeping the knowledge reachable. It is not afraid to be a reference work.
This is one of the more substantial technical sites in CacheRat’s 1,967-domain Ancient Web research list.

If you want the difference between preserving a machine and preserving the knowledge required to keep one alive, spend some time in this site.
