If all else fails, there's also examining the pdf files manually. When
my scanner saved truncated pdf files - with the all-important index at
the end missing - I was able to read the source and discover that the
incomplete pdf files it was building encapsulated raw image files. I
was able to recover the image files by making throwawy copies of the
incomplete pdfs and then deleting the PDF information from around the
images in them.
I do not know if your PDF could have directly included the original .eps
files without modifying them, or if it was a more involved process. I
only mention it as a possibility because I have not had very good luck
with 20-year-old 3.5" floppies in the past.
