(The Quilled version definitely dates to at least as early as 1987, as it was included on the TPUG monthly disk for September 1987 where it's listed as being in the public domain.)
The "Quilled" version was also later sold (1988?) as part of a four-game compilation by Free Spirit Software; where an Apple II version was also listed.
The 1992 shareware release ("version 3") for MS-DOS was included on the disk Tales of Treasure 3.0 with two of the author's other games.
