  Terminals worked for me 2 years ago; they'll work now, MCC just launched about as well as the Infinity landed in Halo 4.

  Tossing my hat in the ring with the solution here. Here's my vid of all collectibles (terminals and skulls) in chronological order in which they are found in the game.

  I'm sharing my video for this achievement (and the Headhunter for Skulls). I've wrote all time codes for the collectibles in the description of the video if you are just looking for a single terminal.
