Embarcadero has Borland Turbo C 2.01 and 3 versions of Turbo Pascal available for download from their site (on their "Antique Software" page), along with Turbo C++ 1.01 if you have a license to some of their more modern software.
Disassembling DOS games has been my introduction to reverse engineering, over the last couple of years. Specifically, Ultima Underworld. The game itself is complex, and a lot of the file formats are already documented, so I'm not jumping into the deep end unaided.
Fun fact: The original Lemmings game is actually encrypted. The first thing it does when loading is decrypt chunks of itself at a time, sometimes copying chunks of code to different places, then jumping into those chunks.
