Amnesia

You wake up in a hotel room in midtown Manhattan with no clothes and no money, and worse still, you have lost your memory. Who are you?

This Electronic Arts text adventure includes a Street and Subway Map to Manhattan (which is handy since the game has close to 4000 separate locations!) and The X-Street Indexer (a code wheel for finding the nearest cross street when aligning the avenue name with the street address number).
