Didn't think my request for disk images would turn into a discussion about old media... I'm more on the side of "the closer to the original, the better" and the images are the closest I'd ever make it. For the record, I have worked with floppies personally and I've seen some weird things happen with old disk images that aren't well-reflected if you just copy the files off (old document-bearing disks come to mind).
I will freely admit I just made an account because this was the oddest and most complex episode yet. I have a question: is there any chance you can release the original disk images along with the contents? Preservation of these weird things are important and this is an amazing preservation of history so far.
