170. Composite video colour (for Master)
      ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
To get a colour signal from the CV output socket, I hear that you can solder
a 470pF ceramic capacitor between the emitter (right leg) of transistor Q12
and the base (centre leg) of Q13. These are located between the CV and RGB
sockets, and although it is a slightly delicate soldering job, it is nowhere
near as tricky as the equivalent modification on an early BBC B.
