Yes, the whole "platform series" from MIT press is fantastic.

The first book in the series "racing the beam", especially so.

Are they complementary? As in, is it worth to read the book after reading the blogposts, or do they tell the same story?

Yes, very much so. The book contains some quite technical walkthroughs of the Amiga, both software and hardware. In enough detail that a technical person will be able to understand more or less exactly what's going on, but without requiring any knowledge about the Amiga.

Conversely, the blog posts tell the story of the Amiga's origin in more detail than the book. So they do complement each other.

Thank you both. I'll definitely have a look at it, I'm fascinated by computer history.
