It's really not needed today. > For a more "authentic" 8088 experience, you could use the assembler that came with MS-DOS 1.25, written by Tim Paterson The author here wanted just his own .asm sources to assemble natively, and not using nasm, and if I understand correctly they indeed depend on the features not present in the old assembler, he writes: "nasm doesn't run over 8086/8088 processors, and I couldn't find a compatible assembler!" It's not that he couldn't find any assembler, but that he couldn't find one that understands the features from nasm he used.
