@sjmulder you can find the compiler, including sources, and some extra tools in the author's website: http://www.graysage.com/cg/Compilers/Amiga/index.html — there's also the CP/M version of the compiler, it kind of works under #MSX-DOS but it's a bit clunky there. The #Amiga version runs even on VAMOS (allows running command line tools emulated under Linux) and the #CPMZ80 version runs under zxcc (same idea for CP/M command line tools).
