The Motherboards are an errand item in Paradise Lost.
The Motherboards are given to the Postal Dude on Tuesday by Papa Desi. They contain RWS new game POSTAL Redux and are to be delivered to Yeeland's Funland. When the Postal Dude tries to deliver the motherboards, he is denied by Yeeland on "moral grounds". After some negotiations, Yeeland agrees to a trade for some weapons. Alternatively, the Postal Dude could simply install the motherboards in the "For Rent" arcade cabinets himself.
