Here are the locations of all Data-Bios and Implant Bios in The Callisto Protocol. Finding all of these unlocks the trophy “Grim Reaper.”
In The Callisto Protocol, Data-Bios and Implant Bios are scattered all throughout the game, enhancing the story. Most of these are easy to miss, and there's only a handful that are mandatory pickups. You can check which Data-Bios you already collected via the Data-Bios menu. The Callisto Protocol is unforgiving, and all Data-Bios you acquire will not register if you load a save that was made before collecting one.
