I can't believe you didn't get a reply earlier.  Inside Mac is a series of
books published by Addison-Wesley and available in technical bookstores as
well as chains such as B.Dalton across the country.  They are somewhat
expensive, so some get by with just a few volumes.  Volumes I, II and IV
are vital.  III is hardware and summary and V is color, essentially.  
Volumes I, II and III are available bound together--IV and V update the
earlier volumes.  There is also a comprehensive index available (another
book).

When you see a reference to II-254, they mean page 254 in volume II of the
set.

You can get along with the IM books if you have someone else's technical
reference, but since that book will have been based on Inside Mac, most
serious programmers want the original available, as well.  However, it
is somewhat frustrating that IM is all Pascal with some assembly.  There
have been some good Mac tech refs published which describe the toolbox 
in either C or assembly language, which is clearly more useful if that's
your native tongue.

Get-a your Inside Mac!  Can't tell the ROMs without-a your Inside Mac!
