What's In A Submarine?

I must be having an ADD attack today with all these short posts. But suddenly, I went from having nothing to talk about to having lots of tiny gems.

A friend IMed me this snippet.

"The Virginias were intended as a cheaper alternative to the $2 billion Seawolf subs,
whose production run was stopped after just three vessels. To reduce costs, the
Virginias use many "off-the-shelf" components, especially in their computers and
data networks."

That's from the the Wikipedia article on the Virginia class submarine. Which was reached by reading an article at defensetech.org that warns of a dangerously degrading attack submarine force.

I think I've got a few TRS-80s and Commodore 64s laying around if they need some spares.
