"Castle Adventure" by Dave Trapasso (1981)

This is a type-in text adventure from Computronics magazine, April 1982, which I don't think exists as a playable game anywhere on the Net. It was originally for the TRS-80 Model 1/3, but my version is for the TRS-80 Micro Color Computer:


Here is a walkthrough map:


The magazine scan was very clear. I mostly only had to add carriage returns and fix a few lowercase L's in place of 1s. Otherwise it was just a standard exercise in using my word-wrap routine and reconfiguring (cutting by half) the PRINT@ commands from the Model1/3 screen, which is 64X16 to scale the messages to the MC-10's 32X16 screen. The program has a somewhat unique screen layout with room descriptions and items being printed at the top, response messages in the middle, and commands entered in the bottom two lines. I had to make new clearing routines for these different zones and I bumped the response message area up a line to just below the demarcation line (now a sequence of SG4 characters representing a castle "parapet") between the top description zone and the message zone. This is because some of the messages obviously take multiple lines on the MC-10 and the bottom of the main message area is used for temporary messages like INVentory lists and random messages, such as when the damsel yells for help.

Finally, I added a pixel art title screen to replace the simple REMarks with the author's name and date info. I didn't include Mr. Trapasso's old address info.

The game "CASTLE" can be played at my GameJolt page under the "Text Adventures" menu item. Just select PLAY GAME, then the "Text Adventures" item, then CASTLE from the Cassette menu and type RUN and hit Enter in the main (green) menu screen.

It can also be played on the Internet Archive at:

You have to press the scroll-lock key, then F2 and then scroll-lock again after the "S" appears in the upper left corner.  That will start the tape loading process.  Just wait, and then type RUN and hit Enter in the green main emulator screen.

  1. OMG, I wrote this game back when we were expecting our first child, who was named after me. Our son recently sent me the links to this game as he shares my like of adventure games. It's nice to see that there are still people around that appreciate these old text adventures. The original "Adventure" was my inspiration for creating this game, & I had great fun writing it. I'm surprised that you were able to find this magazine with the source code. I laugh that my original mis-spelling of "Bear" rather than"Bare" hands was retained! Thank-you very much for keeping this old form of game alive!!!

    1. Dave Trapasso? Thanks so much for your comment. I'm happy to hear you are pleased to see a new computer (the TRS-80 MC-10) receive a version of your game. I'm trying my best to keep these old games alive. Sorry for the delay in responding. I'm not very consistent in keeping track of my blog (somewhat esoteric stuff, and I post so infrequently).

    2. I should also mention that it was a very fun puzzle to unravel.
