I thought about this a couple of months ago in terms of bringing
schematics from work (where we use Orcad 10.5) to home (where I use
gschem) and back again.  Looking around, I couldn't find any
documentation on the Orcad file format, so I tried exporting my design
to an EDIF file and started writing a parser for that in python.  I
never got as far as outputting (or is it outing-put?) the design into
the gschem format, primarily because I couldn't see the point.  I had
no guarantee that once I translated a design to gschem, edited it, and
translated it back to an EDIF file, I would be able to import that
EDIF back into Orcad.  Not being able to see the light at the end of
the tunnel, I abandoned the project, settling for the start of a
parser that extracted some specific information about a specific
design.

I don't think it would be too difficult to resurrect the parser, and I
can see the light at the end of the tunnel for a tool that would take
an Orcad generated EDIF file and produce a gschem schematic (set), but
I don't have any experience at all with the Orcad PCB tool.
