I also spent some of my formative technical years on the Amiga. The Amiga Hardware Reference Manual is available on archive.org for posterity: https://archive.org/details/amiga-hardware-reference-manual-...

I support not throwing out a real, original copy, though :-)

As I get older I enjoy reading 30+ year old technical books and learning more about how those old systems worked, more than I do learning the latest framework or language features. It's intrinsically satisfying, but not so great for the career...
