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.
Indeed, and the same is true of IRIX install CDs, which have an EFS
filesystem.
