Legacy Systems Still Matter

Old code can remain useful long after its original machine disappears.

NaSPA still receives requests for programs written decades ago. Production systems evolve slowly, programmers reuse proven ideas, and institutional knowledge often outlives the people who first documented it.

Our goal is to make this material discoverable by what it does, not merely by an old filename.
