The evolution of a system of 9 MO + 5.4 MO is computed from Zero Age Main Sequence through an early case B of mass exchange, up to the second phase of mass transfer after core helium burning. Both components are calculated simultaneously. The evolution is divided into several physically different phases. The characteristics of the models in each of these phases are transformed into corresponding ‘observable’ quantities. The outlook of the system for photometric observations is discussed, for an idealized case. The influence of the mass of the loser, mli, and the initial mass ratio qi is considered.
