Gaby.de looks like what happens when a working computer-history desk is left connected to the public web for a very long time.
The site centers on CP/M, the operating system closely associated with Digital Research and Gary Kildall, but it spreads outward into Z80 systems, old software, manuals, hardware and BBS history.
The CP/M Center includes downloads for multiple CP/M versions, tools for DOS, CP/M-86 material, FAQs, online manuals, links to original CP/M binaries and sources, the Digital Research Documentation Project, and information about moving CP/M data onto newer PCs.
Then there is ZNODE51.
A BBS survived as a web archive
ZNODE51 was a German Z-System and CP/M BBS. Historical CP/M FAQ material lists it as node 51 in Munich, and the machine behind it was an Altos 580.
Gaby.de’s own virtual museum records that Altos system as a circa-1983 multiuser computer with two Z80A processors, 64 to 192 KB of RAM, a 40 MB hard drive and support for CP/M 2.2, MP/M-80 and OASIS. It had been used as Z-Node 51 until 1992.
The archive now exposes roughly 150 MB of CP/M downloads and related tools.
That is not enormous by modern storage standards. It is enormous in historical context.
The site also keeps a virtual computer museum after the physical private collection was dissolved. There are meeting photos, Z-Fest material, Windows 3.1x resources, Z80 links and old Computer Journal articles.
For retrocomputing researchers, Gaby.de is useful because it preserves relationships between machines, software, user groups and BBS culture instead of reducing everything to isolated downloads.
For webmasters, the lesson is simpler: a small information architecture can outlive the hardware it describes.

The computers moved into history. The BBS shut down. The private collection was dispersed.
The pages stayed up.
