The Amiga, and this era of computing, were before my time. But it is surprisingly fun to browse through some of this stuff, and get insights into the very early days of software development.
My favorite so far is the "Iff Specs Disk", with technical documentation on an ancient container and data format called IFF (Interchange File Format).
Like in the file ea.iff.85 [0], and this section explaining why common data file formats are useful the first place:
"The problem with expedient file formats - typically memory dumps - is that they're too provincial.
By designing data for one particular use (e.g. a screen snapshot), they preclude future expansion (would you like a full page picture? a multi-page document?).
In neglecting the possibility that other programs might read their data, they fail to save contextual information (how many bit planes? what resolution?). Ignoring that other programs might create such files, they're intolerant of extra data (texture palette for a picture editor), missing data (no color map), or minor variations (smaller image).
In practice, a filed representation should rarely mirror an in-memory representation. The former should be designed for longevity; the latter to optimize the manipulations of a particular program. The same filed data will be read into different memory formats by different programs."
Imagine having to explain to a professional developer today why having something like JSON is valuable. Most of us find it obvious.
But there was a time when this kind of thing was not obvious at all; the need for it had to be discovered the hard way, and then solutions invented from first principles.
We really are standing on the shoulders of those who came before us, in more ways than we realize.
