I just had a short glance of the Apple's new book: "Guide to the
Macintosh Family Hardware, 2nd edition", published by the Addison
Wesley. It covers detail descriptions of various hardware components
of the whole Macintosh family line, from the obsolete Mac 128K to
the recent Mac IIfx. I find it much organized and informative than
the previous edition. However, in less than five minutes of reading,
I've found at least two errors in the book. I wonder how these obvious
errors were not caught before the print.

ERROR 1: in table 1-1 on page 2, the memory management IC of the Mac
	 portable is described as part of MC68030, a severe error.
	 The same erroneous table also appears on pages 48 and 88.

ERROR 2: on page 4, the last paragraph says that Mac SE has a faster
	 processor clock (16 MHz) than the Mac Plus, another severe error.

Does anyone find other errors?
