El Desafio de Dunning Cross

You've just entered a boarding school for antisocial boys. The building is built on the site of an old Templar abbey. The students are dominated by a secret brotherhood. You must unravel the mystery surrounding it all until you become Big Brother.

This is a conversational adventure in MS-DOS without graphics, programmed in 1996 by Antonio Cortés Gregorio using the C.A.T. parser, version 3.1, for distribution by the U.T.T. of the ONCE. The interesting thing, according to its advertising, is that it also allows blind people to play. I imagine it's some noise the computer makes when performing actions, but I could only hear a little music at the beginning, and then it asks you to install a SoundBlaster (or compatible) if you want sound.
