It should be a matter of time until someone figures out the DRM, and this is the right place for these historical artefacts to be.
(And if you do manage to rip them yourself, please upload the images to their cdrom collection (https://archive.org/details/cd-roms)!)
If I were the one doing this, I'd go look up NFO files for piracy scene rips of said games and see what image formats they provided, and then look into the software to produce those formats, since there were once a horde of different optical media ripping tools which boasted the ability to effectively produce more complicated image formats than ISOs which would permit exact replication of the media (or software emulation thereof).
A less effort-intensive way of doing this might be preserving an unsophisticated copy of the disc contents along with whatever modifications might be required to circumvent the DRM.
Dosbox emulates cdrom out of the box. Most DOS era games will work with file level copy rips. If you are heavily into DOS games you might want to download 'Total DOS Collection' or eXoDOS. There is also Win3xO for 16bit win games.
