Unfortunately, there seems to be no pdftex.def file, neither in the older distribution file (2015) nor in the present one (2016) :(

The problem is, I have scores (a lot!) of files in plain TeX that I have been produced over the years, by me, and/or shamelessly borrowed from more skilled programmers; an example: code that produces a set of problems with hints and answers, so that the hints and the answers are afterwards printed separately. Even more basic things, like matrix commands (\pmatrix{…} and the like) are not recognized by LaTeX, and are not easily translatable. So, I am still struggling with plain TeX.
