I received an untested 1050 drive from eBay and found the floppy connections were all disconnected (J1,J6,J10,J11,J12,J14,J15)
There are no labels on the connectors themselves to indicate which "J" they should go to and the colors don't match what was shown in the 1050 service manual on page 27. See below the colors associated with my connections.
Can anyone post their connector setup if it is similar to the one below?
