A microprogrammed mix 1009 emulator for the Microdata 1600/30 computer

The design and implementation of a MIX 1009 emulator for the Microdata 1600/30 are presented. Major design alternatives such as allocation of file registers, allocation of main memory, selection of byte sizes and codes are presented in detail. Insights from false starts are treated as valuable experiences. The evolution of the system involved one major false start as well as many minor ones. The major false start is discussed in an entire chapter and the minor ones are discussed throughout. Major firmware logic problems are also discussed in detail. The final system is presented through discussion, a users manual, system flowcharts and listing of the microcode.
