Since I had a hell of a time finding the CompuAdd 810 System Utilities disk after acquiring my 810, I thought I'd share my reconstructed copy that I finally came up with this past week. It's based on a partial copy of a damaged 810 System Utilities disk, plus some missing files copied from a CompuAdd 386/486 System Utilities disk.
I have uploaded it to Archive.org: https://archive.org/details/compuadd810systemutilties
