DOS looking like a mainframe project

Ok, Here's another pet project of mine.. I Have a simple DOS6.22 installed in one of my laptops, and I want to make it look like as much like an IBM (it's an IBM laptop too btw) mainframe as possible. I am working on a vauge memory from a job over 10 years ago when I had an account on the R&D little mainframe. I think the machine was an early AS400, It filled 3 Equipment Racks. This was about the time of the Loma-Preata Earthquake (for non california readers, I forget the year but both San Francisco and Oakland, and San Jose were all effected by it, and that was the one where the freeway collapsed and many of the buildings in SF's Marina District suffered from liquifacation) I think it ran somthing like VM/OS, anyway it had Xedit for a system editor and I have "the heisling editor" which is very much like xedit. Can any one capture screens from a Mainframe like this? I'd love to see them.. Esp. the login screen, A directory/datset screen (where in you put an X near a file and hit enter to edit the file.) and any other sorts of menu screens. Thanks.
