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.
