I think you're correct, a lot of the earliest cracks are essentially undocumented.

But in later times there was a good community of cracking software for PCs, and those notes continue to live on despite the unfortunate death of the curator/collector, +fravia.

Here's a decent mirror, for example:

At one point I used wget --mirror to download the whole site, and that was back in the early 90s.
