Someone mentioned a book about computation machinery. I thought it was in this discussion, but I couldn't find it here and it's near impossible to google here.

The person who mentioned it said that it explains the history of building computers and gives you a very deep understanding of how they implement computation, and its interface with the software inputs.

This is something I really wish I understood better, so if anyone knows a book like this, please let me know what it is. Or, if you know of any good resource on this topic, please post it.
