  We present the first milli-arcsecond resolution radio images of a radio-quiet
quasar, detecting a high brightness temperature core with data from the VLBA.
On maps made with lower-frequency data from MERLIN and the VLA jets appear to
emanate from the core in opposite directions, which correspond to
radio-emission on arcsecond scales seen with the VLA at higher frequencies.
These provide strong evidence for a black-hole--based jet-producing central
engine, rather than a starburst, being responsible for the compact radio
emission in this radio-quiet quasar.
