Look you moron if the 1000 series is T 1000 Then guess what s the 800 series is MORON IDIOT And as stated here in one of the discussion in this page I agree with Christopher Thomas below regarding unclarified sources for this article Specifically I take issue with the entire Differences between the 800 and 850 series section because I contend that there is no such thing as a T 850 Stan Winston Studios which designed the terminators for the films confirmed this to me via e mail when I wrote to them asking their opinion Their response direct quote I m not sure where the T 850 came from As far as I know Arnold s Terminator has and always will be the T 800 model 101 Now the robot Terminators in T3 are T1 s and Kristana Loken is the TX I hope that clears it up While the term T 850 is somewhat widespread on the internet even extending to T3 related merchandise such as action figures its origin is to my mind something of a mystery Rich Stan Winston DESIGNED the Terminator and he says it s T 800 Now shut the fuck up and change it back you idiot
