Come to think of it, perhaps a sub-$50 B/W QuickCam would make a
 cheaper reader than a scanner. 
Good idea.  I hadn't thought of that.  I think there's Linux software
for the QuickCam.
  I know the video/scanning route sounds like
technological overkill.
 What's wrong with that?  :-)  It reminds me of my day-dream to
 rescue audio cassette data using PC sound card digitizing. 
Been there, done that.  There's a commercial program to convert .WAV
files of C-64 data tapes back into usable files.  It also works if
you hook a real C-64 datassete to the parallel port.
  I like these novel solutions because they are less
dependent on
 esoteric hardware, and the core - the software - is more portable
 and transportable into the future and to users who need it. 
Yes.  I have enough forms of esoteric media that I have a vested interest
in keeping them readable.
  Sounds like Ethan has more spare time than I do,
though! 
Perhaps.
