I would like to buy my father Bill a computer for his upcoming birthday and wonder if anyone has specific suggestions as to hardware which might best work for a person with PD. I will get him a DOS machine so that I can provide some minimal "on phone line" support for him. He has tried my mouse (attached to a laptop...you have to use your thumb to move the trackball) and seems to have difficulty with it. I suppose a regular mouse might work better. Any suggestions?
