Jason,
yep, that's it ! That's exactly what I got.
The mechanical translation of the TXT is not really necessary, there's an english version available in the same dir where the ZIP resides - with the disadvantage of having to translate the CTRL and ALT keys again. Anyway, the steps you listed below are exactly what is required.
The English EXE is there as well, but gives access denied - we have to stick to the german version in the ZIP.
Since the lunar lander is a "source code", it should be easy to translate it :-)
Next to figure out how to load and run a "native" program, like the bkjck or bitc1 stuff ...
