I work for a Radio Shack here in Los Alamos, and it may be that the easiest
solution to your brother's problem would be a trade in.  Radio Shack will take
trade in's on old mother boards and if you pay them around $80, they will give
you a fully functioning one.  

Of course, one has to weigh this price to that of sitting down with the tech
manual, a scope, a cup of coffee, and probably 3 or 4 spare hours just hunting
down the problem.  In the end, you wind up with a working board no matter which
route you take.

Best of luck...
