P.R.I.M.A. 3000
(from Prima Game Guide promotional code)

This is a custom version of the P.R.I.M.A. 3000 computer that players could redeem if they bought the “Sims 4 Collectors Edition Prima Game Guide” back in 2014 when the base game of The Sims 4 was released.

Since there's no way to unlock the item, like with the rewards from recent live events, I've set it up so that if you put down a lot that contains the original item but missing it, the game replaces it with my own custom one as a fallback object.
