Don Maslin collection status

After being contacted by Don's niece, I went down on behalf of CHM in July and retrieved every box of media that was in the storage unit from his garage. I've spent several months going through everything, including the PCs that were there, and could not find what I had assumed were disk images that are described in the 'sysdisk.txt' file that Don maintained which I've attached. Does anyone have any contacts with the San Diego folks that knew Don that could help with figuring out where these images would have been? It's possible either they were on more modern PCs, or on a CP/M system. CHM is not willing to take everything that is still in the storage unit (mostly paper and the computers that were in the garage). I'm going to have to make a pretty strong case for trying to recover any of the systems that are still there.
