worth the trouble?

a friend just dumped off these two cattleyas on my doorstep. He said that they are at least fifteen years old, and that he "inherited" them after his grandmother passed away. As you can see, they have not recieved much TLC. Take a look, do you think they are salvagable? I suppose I should look at the roots. I do see some aerial roots that have taken off recently, but I can't make out any new growth other than that. What would you do?
