The Serial Access Supervoc 1 (or SASV1) was a robot built on Kaldor.
SASV1 was built using blueprints found in Taren Capel's cabin on Storm Mine 4. It was hoped it would avoid the problems that D84 had experienced. The robot developed the ability to dream. It eventually confused its dreams with reality, thinking it was Taren Capel. SASV1 started controlling other robots and having them kill anyone who opposed it. The Fourth Doctor was finally able to stop it by blowing it up. (PROSE: Corpse Marker)
