This post is off topic but for me very interesting. I have always been interested by the computer revolution and have read most of the classic books on the history of it, including Accidental Empires by Robert X Cringely and of course Hackers: Heroes of the Computer Revolution by Steven Levy of which I have 3 copies of, one of which has circumvented the globe twice with me.
The Apple book looks great and I will probably order it, whether I would build an Apple 1 or not is another thing. I did build a Microtan 65 around 1980 - which I still have in my loft along with an oscilloscope I built from scratch in 1979 / 1980. It would be great to see a detailed book like Apple 1 book for some of the other classic computers such as the MITS Altair 8800 - regarded as the first real micro-computer. Great idea for a book though, how to build a classic computer.
