A bug in the TRS80/CoCo versions:
In the "else" of the "climb" in room 80. The "move to" should be in the block above it. The MoveTo is always the last thing that happens everywhere else. It should be here too.
I updated the content to the latest markdown format.
I found a 6809 emulator on github. I am wiring it up to the pyramid site so you can play the game in emulation. That'll work for the other games too ... except for Madness and the Minotaur which has real-time interrupt driven features.
