Ali - you bet I will! =P

Chuck - thanks for the notes. I have no idea what it actually came from but
I imagine it did come with a Display writer system. No problem with the
format in which the data is stored, I can always present a more reasonable
storage interface to the user via FTP or something. EBCDIC conversion or
simply writing arbitrary bits is fine with me.
