Well, perhaps my choice of word wasn't the best. I certainly didn't mean 
to say that the subject matter should be made "easy". Computer 
restoration is challenging and difficult, I acknowledge that. What I 
wanted was to make the subject more approachable.

:) And I try to read (and understand) most of what you write, even if 
it's not directly related to what I collect. What is this HPCC that you

When I think more about it. I think I want a book that guides me through 
restoration of computers from digital between 1970 and 1980, since that 
is my main interest. I realize that a book about restoring micros from 
1980 and onwards would be a very different book.

Still, I don't think either of those books exist.
