On first thought, it might seem strange that another book on the 8080 and Z-80 should appear at this time. Z-80 CPU cards generally became available in 1977 and the 8080 CPU is even older. But the Z-80 computer seems to become more popular with time. For example, the TRS-80 Model II announced recently by Radio Shack, and Heath's H-89 both use the CPU. High-level languages such as Pascal, APL, BASIC, FORTRAN, and C are now run on the 8080 and Z-80. Furthermore, Microsoft has available a Z-80 CPU card that can be easily inserted into the Apple II computer. There should be an increasing interest in the 8080 and Z-80 CPUs in the coming years, and I believe, a great increase in the number of 8080 and Z-80 programmers. So, there is a growing need for a book that covers programming for the 8080 and Z-80 assembly languages. |
