Hi,

I have a couple of servo motors out of an old Olivetti printer which I'd 
like to try to use, however, I can't find any information about the 
encoders fitted to them. The encoders are in flat brown plastic 
enclosures on the end of the motors and have 7 pin plugs with 6 wires 
connected (the motor power wires are separate). Looking inside there 
appears to probably be 3 photo sensing elements and a clear plastic 
encoder disk with, I think, 100 prismatic lumps on it and so I assume 
that the 6 wires must somehow represent a quadrature encoder with index 
mark???? - or maybe a quadrature encoder with two power connections - I 
don't know. Has anyone come across this type of motor and worked out the 
connections or is there some way I could work it out for myself?? thanks.
