I have a 1989 copy of From The Ground Up I paid $20 at the time. I saw a
updated copy for $50. I don't like the 1989 copy I have, I think it is
poorly written and doesn't explain the topics properly. If anyone has the
updated version is it the same stuff inside or is it completely re-written
and easy to understand? If that book is out of the question are there any
other titles that a novice could read and have the concepts and topics
explained properly and easy to understand.?

Thanks in advance
