The original listing is in Applesoft BASIC. Unofficial ports are known for C16/Plus4, C64/128, PC, TRS-80 and VIC20.
The (unauthorised?) Atari 8-bit port was done by Nigel R Haslock in 1982 and published by The U.K. Atari Computer Owners Club software library. First advertised in The U.K. Atari Computer Owners Club newsletter, issue 2, 1982, p. 18.
There is an unofficial PC port entitled Tommy's Manor, dating from 1989, which was produced by "Tommy's Toys". There was a charge to register the game!
Another MS-DOS port of the game has the credit "Translated by Allan and Andrew Lee". A TRS-80 Model 4 type-in, also attributed to the same "authors" was published in TRSTimes Volume 6, Issue 4, July/August 1993; where no credit was given to Randy Jensen.
The original game was enhanced for Coleco ADAM by an unknown author and released by ADAMagic, on their "Adventure Pack 3" compilation, as Ghost Buster without any credits to the original author.
The original game was translated into Dutch as Korenvliet. It's not clear if that version was officially sanctioned but the Dutch game was ported to various systems and was also translated back to English, with extended descriptions, as a TADS game by Alexander van Oostenrijk in 2016.

Very crude, but not the worst as magazine listings go. The PC version that can be found in the Internet has a bug that mixes up some map connections. A fixed version is provided.
