Thanks, essexboy. I'd played with dosbox some years ago to get some old DOS games running (biggest problem was getting the frame rate adjusted properly for a modern system), but never thought of it in terms of Win apps for older Win versions.
My biggest gripe with it is that despite being intended for Windows, it badly needs a reasonable GUI to help with the setup process, mounting drives and moving the appropriate apps. Fortunately my son's quite familiar with it, and can do that part far easier than I could.
Thanks again, and best,
Mike
