Paul, VAX CD-ROMS generally are not ISO. ISO implies the ISO9660 file system, but many VAX CD ROMS are in native VMS Files-11 format. Some Windows utilities don't handle these so you need third party software to create an image of these CD's. Generally it has a .iso extension but as the content is not ISO9660 you can't mount it on Windows or Linux.
There a couple of utilities that will convert arbitrary files to image files. I tend to use CD Burner XP https://cdburnerxp.se/en/download but you need to click "More download options" and use the "without install core" versions....
