I seem to remember there where some important things in there that
didn't quite match up. Mine was actually misprinted and had one of the
later chapters printed twice. Whatever was in the missing chapter must
not have been that important.
It taught me binary and hex and basics of CPU architecture, though.
That Z-80 was a hot little chip. Too bad IBM went with Intel instead.
Imagine a Zylog based IBM PC running CPM-86 in 1981!
OK, I better shut up now.
