My family's first computer was a TRS-80 Color Computer 2. We later acquired a CoCo 3. I've had some luck in getting game identification questions answered on the Science Fiction and Fantasy Stack Exchange, but this one seems to have stumped people. I suspect that part of the problem is that, based on my memories of being able to access the game's BASIC source code, it was likely a hobby program one of my siblings inputted, possibly from Rainbow magazine. In general, SE disapproves of cross-posting, but this is an older question, and I suspect that this group is more likely to recognize it, since they might have inputted the source code themselves.
So, would it be alright for me to cross-post this question?
