After the data declarations were moved into seperate include files the sources refused to compile on a pdp-11. Apparently, the pdp-11 preprocessor can only handle a limited number of include files. To create a version on a pdp machine, you will probably have to combine the include files into one include file per source file in order to get it to compile. Not all source files may need this extra bit of work. You'll just have to try and compile and fix those that the compiler complains about. I no longer have access to a pdp-11 machine, so I can't do any testing on it. (As stated in the README file, I have run this game on a pdp-11/70 before the include files were created.)
