I've got an original Apple ][ reference manual (red cover) with the hand annotated ROM listing.
Also have SMALLTALK-80 book with it's railtrack diagrams of syntax on the inside covers.
What's really interesting about the AI mania we're in is that no one has shown that what we have now will get to AGI and how. We have great models that simulate reasoning, but how close are they?
How do we measure their quality? Benchmarks? Tooling?
