Mentioned it in another reply, you'd probably want to start with the MASM and LINK from the MS-DOS 2.0 release. https://github.com/microsoft/MS-DOS/tree/master

Also, as written in the blog post, the .ASM files are not the original sources, more a temporary expansion of these for the given target. Looking at their binary form, all .ASM files end with zero characters instead of, for example, 0x1a with which .H files end. It can be that some tools (different than those originally used) have problems with the zeroes at the end?

  That's a good observation. I tried stripping zeroes, but unfortunately it's the same error message.

Unfortunately, I can't get MS-DOS 2.0 to run in DOSBOX ("Invalid COMMAND.COM") and running MASM.EXE directly gives me some really interesting errors (looks like it's reading uninitialized memory). I think you're on to something here, though!

  Good job! I'm going to throw some cycles at this, this holiday weekend. https://github.com/lpsantil/GW-BASIC https://github.com/lpsantil/GW-BASIC

  DOSBOX can't run older DOS programs, try my emulator: https://github.com/dmsc/emu2 https://github.com/dmsc/emu2 , ASM86 runs in it.

Probably you want to try out PCem when dosbox doesn't do the trick. Was a lot of fun for me! I made a small page about PCem here: https://juangacovas.info/doku.php/windows/howtos/pcemu-page https://juangacovas.info/doku.php/windows/howtos/pcemu-page
