Patrick,

FWIW: Look for sarlacc_schem.c in the utils/src directory.

I used this as a template for a HiWireII to gschem translator project (never
completed and abandoned due to other priorities).

Exerpt follows below.

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.
