Do you depend upon modern computers, or are you a creative spirit who
can push the limits of your old hardware in order to fulfill your
everyday needs? The Retrochallenge is where you find out.
What are these challenges? If you enjoy creating original artwork,
music, or programs on your legacy computer, then the creative
challenges are for you. The second challenge is simply using a
qualifying computer through the month of July, in a competition to see
can survive a month without the latest in gadgetry. The third
challenges judges how well you could communicate with the outside
world on a retrocomputer.
