Instead of using open(2), use the apollo-specific calls in the ms_$ family which
will permit you to map the file directly to a virtual address.  Then, you can
treat this as a large buffer and write(2) it out to a different disk file, which
can then be opened and manipulated using dd(1) to get ebcdic -> ascii conversion,
or whatever.
