They _are_ 'ISO' images but in a format which Windows 7 or whatever burning
program you're using doesn't understand.
I used Nero (or Daemon I think) to write CDs for my VAX but there will be
plenty of other programs equally suitable.
You don't need to do anything special, just treat them as an ISO image and
let the burning software get on with it.
Once written, Windows won't be able to read them so don't panic. If the
burning software includes verification then it (not Windows) will be able to
read them back OK.
(I'm using VMS v7.3 but I'm sure this is no different).
Generally AFAIK the CD readers on Vaxes (Vaxen - ugh!!) and Alphas will
deliver 512 byte blocks but this isn't relevant for the image itself.
