80 Columns for the Commodore 64 by Gregg Peele and Kevin Martin - A utility / demo of the Commodore 64 as it would look if it have an 80 column display.  Kind of neat to write some simple BASIC programs that can take advantage of the extra columns.  Just be sure to do a "NEW" command before starting your BASIC coding and you'll have 26,627 bytes of space to work with.
