I was looking on amazon.com for a link to a book called “Fire in the Valley”, which I once bought from a bargain bin for about $5. It’s the history of the PC — starting with the Altair in the 70s and continuing with the emergence (and sometimes subsequent failure) of Apple, Microsoft, and various other tech companies. Very interesting book. I found the link here, but the amazon search also found another book with a similar title: “Fire in the Valley: Female Genital Massage“. Not the same book.
