One of the games I have on my radar is Joel Mick’s Burial Ground Adventure, which is from 1979 and not that hard to find.
However, the game mentions a followup work called “Damsel in Distress” which I haven’t been able to find anywhere. It is mentioned in this comment from 2014:
I found the complete Odyssey series by Joel Mick (Damsel in Distress, Treasure Island, Journey Through Time) on Marmotking’s Vintage Computer Site, although it appears to be down at the moment. I tried the first game, but I don’t think I’m as patient as you when it comes to tackling primitive parsers. The game gets confused with the objects Horses and Horseshoes, for example. I didn’t get very far.
Marmotking’s Vintage Computer Site appears to be completely defunct, and archive.org barely has a few shreds. Since it’s a game that apparently was on the Internet at some point, I figured I’d throw out a request — anyone know where I can find this?

I’m the guy who posted about this game on Gaming After 40. I downloaded all three games of Joel Mick’s Odyssey series (Damsel in Distress, Treasure island, and Journey Through Time), all for the TRS-80, before the website I mentioned was shut down. I sent the TRS-80 cmd files to your gmail account. let me know if they work.
Didn’t come through; I sent a message.
Hopefully, it came through now. I sent it two different ways, just in case. Let me know whether or not you get it.
