If all you need is the binary, there are old pdftex.exe's on CTAN: mirrors.ctan.org/obsolete/systems/msdos/pdftex/pdftex.exe mirrors.ctan.org/systems/msdos/djgpp-contrib/pdftex-djgpp/pdftex.exe They are part of whole distributions, so if you need more, maybe one of them will suffice. Good luck, Karl
