Cooper

Cooper is the handheld computer that is owned by Greta Grobler. In "The Terrifying Tales of C.J. and Friends", Cooper was rudely nicknamed "Ogre Freak" by Rigalli because Cooper's batteries died.

Appearance and Traits
Cooper is green with four buttons beneath an LCD screen. The screen displays an animated anthropomorphic ogre. A gray stylus or antenna rests on Cooper's top. His serial number is 57646.

Cooper is first seen in "The Girl Was Trouble", in which the entire episode was focused on Greta's efforts to retrieve the device. She eventually does and the Cooper has been an integral part of the gang's endeavors ever since. It last appeared in "Lax". Cooper has advanced artificial intelligence, enough so that it can talk and find a great amount of information when Greta calls for it.

Greta received Cooper for her tenth birthday (March 23rd, 1998) and (fictional AI aside) would have been cutting edge for the time. The amount of RAM (16MB) would not have been particularly unusual but PDAs with true wireless internet access did not start to appear until May 1999 with the release of the Palm VII. Furthermore, Cooper's processor speed is mentioned as being in the 300 MHz range which would be roughly double that of the fastest PDAs of the time (although the writers could not have known that PDA CPU speeds stagnated for several years immediately after the episode aired).

Trivia
Cooper was named after Sheldon Cooper from The Big Bang Theory.
