Pardon me if this is an old rehashed issue, but
What kind of computers do they use on the shuttle ?
Why do they need 5 of in case they disagree ?

I've heard they have very small memory ("less than a typical
modern PC" according to one astronaut)
Why don't they modernize ?

Please e-mail responses if this has been covered already.
