What I'm wondering is, why did your father refused to use computers? That's way beyond a mere lack of interest. So, could you give us his stated reasons, and your speculations regarding his real reasons?
Let me try an analogy here. I hope I do not miss the point because of cultural differences: I think he comes from a time where using typewriters at an office was perceived as the job of a female secretary. :-). A computer looks much like a typewriter from an outsider perceptive (a keyboard and monitor to look at instead of paper).
