I can understand what tempted Don Woods to make his additions in 1977 to create the classic 350 point version. The object is to enter an old factory building where the world's only remaining copy of Adventure is reputed to be stored, and to leave with a tape containing a copy of the program.Īs I worked on the rooms in the Bedquilt (“Under Construction”) area of Crowther's original code I really could sense where his patience with the project petered out (sometime in 1975 or 1976) so I also ended up adding a few unique elements of my own to “complete” an unfinished work just begging for completion. Tower of Mystery is a BASIC program designed to illustrate some of the concepts of adventure programming and to serve as a starting point for writing your own adventure programs. Here's a description of the program from that book, which fittingly contains a story reference to the original Adventure: Neil uploaded a PDF to the group of a simple text adventure program "Tower of Mystery" used as an example in a Compute's Guide to Text Adventures (1984). I was also greatly aided by Neil Morrison of the TRS80MC10Club group on Yahoo. Virtual cassette files can be loaded via the File menu of the emulator. To play the game load the file "COLOSSAL.C10" after typing CLOAD and hitting in the emulator. See: for the Virtual MC-10 emulator, which includes the game in the JimG sub-directory of the cassette directory. Just remember that when loading and prompted to "Press Play" you must select the file name containing the desired virtual "COLOSDAT" cassette file. The same file name "COLOSDAT" is used for each save, but in the TRS-80 MC-10 emulator (VMC10.exe) you can save the resulting virtual cassette file to any file name you like in order to differentiate between different saves. ![]() You are also prompted each time the program is run if you wish to load a previous game. The QUIT command not only quits but prompts whether you would like to save the progress you have made. The UNLOAD command will perform the same function as the more standard "drop all" command of other adventures. The HELP command will provide some rudimentary aid. The SCORE command will tell you how you're doing and if you have won. In reconstructing the game play elements I was greatly helped by Renga in Blue's "Observations about Crowther's original Adventure". I only made a very few tweaks where directions were quite clearly messed up or to eliminate a few NE, NW, SE and SW (diagonal) directions. I had to wedge it into 20K of my favourite 8-bit the TRS-80 MC-10, so some of the descriptions got “edited” a little, but I was able to transfer the map info from the data file into Basic DATA statements, so it's a fairly accurate rendition of the original map. My version contains only the numeric room movement info and the room and event text descriptions of Crowther's original game, reputedly written to entertain his children in the wake of a marriage breakup in the mid 70s. This is not the classic "350 point" version created by Don Woods by the addition of many novel elements to Crowther's original source. I re-coded the program into Basic from the Fortran source code and data file that Crowther's wrote for the PDP-10, which was recovered a few years back from old backup tapes. I have fixed and finished certain uncompleted elements in the code and changed a few things to create a few additional challenges to provide a more complete game experience of what was obviously an uncompleted "work in progress." For Retrochallenge 2015 I ported to Microsoft Micro Color Basic Will Crowther's original Fortran source code for what became "Colossal Cave" or "Adventure." The new basic source code should be easily shifted to other Basics. ![]()
