I'm currently in the Main Library of University Of Malaya. One of the best things here is that, sometime there is treasure in this library, and no one bother to borrow it. Most just get references, past exam papers, academic books.
Treasure, the book "Fire In The Valley: The Making Of Personal Computer" is such a treasure. It have inspired, the film "Pirates Of Silicon Valley". But really, The book is a lot more.
It describe, on the age of computer hobbyist, the MITS, and some old microcomputer company, that don't exist anymore, such as IMSAI.
I won't all it a text book, but still it is an interesting read for computer history buff like me.
