It's something called a 'BT 600' plug IIRC. COnceptially it's like an 
RJ11, in that there are metal contacts on one face of the plug that mate 
with spring contacts in the socket, but while the RJ11 os almost square 
seen end-on, the BT plug is much wider than it's high (say a 2:1 ratio). 
the cotnacts (6 positions, for most domestic installations only the 
centre 4 are fitted) are on one of the long faces, the latch is on one of 
the short sides. Which side the latch is on indicates whether it's a 
'line' or 'handset' connector I think. This conenctor is always white, 
there was (I've not seen one for years) similar black connector with 
different key notches (so you could not fit that in a telephone socket or 
vice versa) which was used for 'data' applicaitons, I believe the 
Sinclair QL had them for serial and joystick ports. 

I would think any of the UK electronic compoent distributors would have a 
picture on their web sites. Try http://www.rswww.com/ or

Ah, when I'm doing hardware hacking (i.e. almost all the time) my iron is 
always turned on. I know I am going to need it.
