I could not find the original macrotized version. As history tells it there was a version of this code that was written in a bunch of macros that were parsable by humans and they emitted assembly code for a wide variety of machines and architectures (from the 8080 to the 80286). When I wrote the BASIC interpreter that runs in your web browser (using Java) I modelled it after GW-BASIC as this was the BASIC that had the most number of test cases I could find. Given that we've got DOSBox for running DOS in your browser this should be portable to that sort of environment right? I know playing HAMMURABI and TREK isn't very engaging to the cool kids these days but they were a big component of the early microcomputer "revolution."
