I just did a search and found collected PDFs of all of the Inside Macintosh volumes. (For those who don't remember, these were technical manuals on how to develop hardware peripherals and write software for the Macintosh.)
My first computer was a Mac LC; I got it as a 10-year-old, and learned to program on it (and its replacement Centris 660AV) as a 12/13-year-old. At the time, the Inside Macintosh series was way too advanced for me; I lived on little Pascal game creation tutorials. It's interesting to look back on them now, as a professional programmer with ~25 years of experience. It actually looks pretty simple now. Also interesting to find that I can still read Pascal, even though I never used it professionally and haven't worked with it in 30+ years.
I remain convinced that the 1990s rewrite of Inside Macintosh (which can be found here on your site: https://vintageapple.org/inside_r/) was the best documentation Apple ever produced.
