Here you can find the first version of my rEd-MMIx software for MS DOS. This moment it may be called alpha-version, because it is not a final variant and I'm constantly improving it. The only thing I can promise is that E-MMI works and can execute simple programs.

E-MMI program now can execute about a half of full MMIX instruction set. Using this software you can easily input, test and debug the simplest MMIX programs. As I suppose, main E-MMI software advantage is its interactive mode: all MMIX software I have seen before, work with files. Another distinguishing feature of E-MMI is the organization of input and output. My program has standard I/O functions similar to CP/M operation system (also inherited later by MS DOS). To call any I/O procedure in E-MMI you must use TRAP 05 instruction with definite parameters.

To help you in learning E-MMI, I have prepared the detailed step by step instructions how to realize one typical MMIX program on my software.
