Xibalba Model 100 Legacy

The following files are mirrored from Shawn M. Brisbin's website (xibalba.com) that had a collection of TRS-80 Model 100 Software until it went offline around the time the Mayan calendar rolled over. I think Mr. Brisbin would appreciate the work we've done to dig up his long gone site as he was (is?) an archaeologist with the University of Calgary. (You can read about his work with the Belize Valley Archaeological Reconnaissance).
