Star Wars: Knights of the Old Republic/HK-47

HK-47 can join your party if you purchase him from Yuka Laka, the Ithorian proprietor of the droid shop in Anchorhead on Tatooine. You can then speak to him at any time when he is added to your party or you're aboard the Ebon Hawk, where you'll find him in the swoop hangar with Canderous.

Repairs
Restoring other parts of the core requires an increasingly high Repair rank of your main character for each of four consecutive repairs. Aside from unlocking further dialogs, HK-47 receives bonuses after each successful repair.

If HK-47 joins your party before you've found a fourth Star Map, these repairs are no longer possible once you've left that planet and subsequently been brought on board the Leviathan, after which this quest will be completed (so these repairs aren't actually necessary). To achieve minimum Repair rank 17 to complete all four repairs, it's advisable to buy Calrissian's Utility Belt (Skills: Repair +3) and boost Intelligence using Master Valor (Intelligence: +5 from character level 15) and the Memory Package implant (Intelligence: +1, if possible).

If HK-47 doesn't join your party until after you've escaped the Leviathan, these repairs are still possible but you cannot technically complete this quest. If you have access to the Yavin station, then after finding the fifth and final Star Map you can also buy the Advanced Agent Interface (Skills: Repair +7) there. This may be a preferred option if your starting class is not a Scout and your Jedi class is not a Jedi Consular (otherwise Repair is a cross-class skill), particularly for a dark side character who wants to add HK-47 to the party on the Star Forge.

Leviathan
If you try restoring some of his memory a fifth time before finding a fourth Star Map and subsequently being brought on board the Leviathan when you leave the planet:

The proper stimulus is identifying whoever originally sent him on that assassination mission in Mandalorian space…
