Hmmm, I don't know if it is the same but...I have a Nikon FA that displays something unintelligible (like F--) untill, a roll of film is in place **AND** wound to the first frame. A careful reading of my instruction book even says this is what it is supposed to do...again, I do not have an 8008 so, not sure if this is even related.
PS I've bought a bunch of stuff from KEH. Was even desperate enough to sell some stuff to them once. Never had any troubles. Only once, maybe twice, asked for a return and refund.
