There are almost 30 Suit Chipsets in Prey, and you'll only even be able to install eight at any one time. It's important to note that Chipset locations in Prey are always the same, but each playthrough might give you a different chipset in any one particular place.
Below are lists of each suit chipset and their possible locations, excluding the suit chipsets you get as part of mandatory objectives.

Chipset Reward For Treasure Hunt Objective
The Treasure Hunt objective, wherein you find a series of treasure maps and then investigate their locations to reveal a code, will grant you either a positive or negative chipset. If you actually investigate every location for every treasure map before entering the code on Abigail Foy's computer in the Crew Quarters, you will be rewarded with a great chipset. If, however, you cheated and entered the code without investigating any of them, you will be given a chipset with only negative qualities. Both are below:
Adverturer's Toolkit: Increased Fabrication yield, increased wrench critical hit chance, better flashlight efficiency, and faster crawlings peed.
Game Master's Ire: Reduced Fabrication yield, less-efficient flashlight, reduced crawling speed.
