And the 8.2 GB archive that COMPAQ DOS 3.31 was sourced from is here:
"The DOS Memories project is a collection of over 2,400 DOS-based programs from 1980-2003, primarily games and entertainment software. All are self-contained in .ZIP or .RAR files, with installation media contained within. These should not be considered canonical game images, but reference points for study."

I've added copies of a British disk set of 3.31D to https://archive.org/details/compaq-ms-dos-3.31-d-imd.-7z which may be of interest. It was archived using IMDISK but now I have a Greaseweazle I might have to do another dump.
