The level 2 research data chip can be found in Viking Square, on a random floor that isn't the ground floor. The room that has the chip is a large, square room with a vent in each corner, and likely has four doorways. The chip is found in the ventilation system, laying on the ground near a deceased cat.
On F05, the only journal of the sector can be found in a square room, similar to the room with the chip but without the vents. In one corner of this room is a corpse with the journal and a side bag on the ground; in the side bag, a marsmari D can be found, which is the only known place where an improved marsmari can be found (outside of production, of course).
