This is a text adventure modified to work on the TRS-80 Micro Color Computer ("MC-10") using Micro Color BASIC from the author's published source code in TPUG Magazine June/July 1985 pp. 8-12. The game is a sample adventure described in an article "Do-It-Yourself Adventure", which provides the basic building blocks for creating your own text adventures in BASIC. TPUG Magazine was the newsletter of the Toronto Pet Users Group, one of the largest Commodore computer clubs in North America in the 1980s.
