I recommend that you track down a copy of Oracle5 for MS-DOS (I may even
have an old copy around here somewhere).  Is it the one in the grey
binders (three of them in a box arrangement)?  You will not be able to
read that data without the corresponding Oracle system code.  You will
also need a complete (or mostly complete) database (the control files, the
system tablespace, etc.).

If I understand the question, the Oracle system code gets the physical
information about a database from its CONTROL file(s).  That contains a
map of the corresponding physical files that make up the logical database.

Hope this helps.
