It looks like you had it on that disk! The original filename is TVF.
We first started getting new Doom games from a friend of mine who also had a TI. I can't be certain, but I believe that Volcano Fortress was one of the first games released, and it may have been a single, the only game on the disk.
The Doom Games compilations (I think there were three?) came later and had the Kmart game, the Doctor Who games (two of them), and so forth. I bought Doom Games 2, but the rest I got copies of from my friend, so they got all scattered about...
Why the sudden interest on my part? Because one of the final dungeons in my game will be "The Volcano Fortress". Possibly with some fellows named Behnke and Reiss wandering about...
