Var skulle Anakin ha fått C-3POs språkdatakärna?

Anakin byggde inte egentligen C-3PO. Han byggde om honom.

Från Wookieepedia :

Originally activated on Affa in 112 BBY, C-3PO had served as a protocol droid to the emissary of the Manakron system. Nearly eighty years later, he was gutted and discarded on the streets of Mos Espa, a city on the Outer Rim world of Tatooine. After being rebuilt by the Human slave Anakin Skywalker, C-3PO served Skywalker and his mother Shmi for over ten years, performing household chores and helping Skywalker earn his freedom by winning a pod race.

Så ditt antagande var korrekt: C-3PO var byggd av en regering för regeringens användning, och hans första användning var att följa med en ambassadör, ungefär som när vi först ser honom i A New Hope .

När Anakin hittade honom var C-3PO ett huvud och ett slitstarkt chassi. Han pralade dock fortfarande på ljudkabeln, liksom en standardprotokolldröm verbobrain och kommunikationsmodulen . I synnerhet kommunikatormodulen är de språkliga färdigheter som C-3PO demonstrerade:

The TranLang III Communicator module was a late generation communication module incorporating millions of galactic languages, installed in 3PO-series protocol droids and LOM-series protocol droids.

Det verkar som om språkdatabasen fortfarande var intakt i TranLang III Communicator-modulen av det kasserade robothuvudet som Anakin använde att rekonstruera C3PO. Från Wookieepedia :

[C3PO's] head and gutted chassis had been discarded in a street of the city of Mos Espa on Tatooine, and were discovered by two Human youths, Anakin Skywalker and Kitster Banai.

...

C-3PO's gyro-balance circuitry was several decades old, but Skywalker was able to use scrounged and improvised replacement parts to make the droid functional again. C-3PO boasted sound wiring, as well as a standard protocol droid verbobrain and communicator module, but Skywalker could not afford even the simplest of droid coverings, and as such, left the droid's wiring exposed.
