I have a copy of version 1.0 on 5.12" floppy diskette from 1988. Is this of any historical significance or collectable? On second thought, it looks like it's a demo disk for version 1.0. Here's a picture of the disk.
Amazing, and very enjoyable!
Dear @Peter did you ever try to run these on any machine? Do they work?
Have you seen this? - http://www.mathematica25.com where you can find
The Mathematica Story: A Scrapbook
with a button to "Contribute your thoughts, pictures, and stories".
Lucky you. Does it come with the original version 1.0 source code also? :)
I have 2.2 Mathematica, and it still boots also ! here is screen shot.
It's definitely cool
