The current WIP code is to be found at

https://github.com/erichVK5/translate2coralEDA

Your easiest options, in order of decreasing simplicity, are

1) convert to ascii format, after which further conversion becomes quite
simple. There is a pcad2kicad utility on sourceforge; pcb-rnd can then load
kicad format and save in gEDA pcb format, or you just keep working on it in
pcb-rnd.

2) turn gerbers into layout elements, if you have gerbers.
translate2coralEDA can do this better than translate2geda because pcb-rnd
supports arcs in footprints, as well as polygons. You will lose distinct
footprint elements this way.

3) use the altium pcad viewer which is free to download. Make screenshots,
and use --bg-image in PCB or pcb-rnd to layout the board. pcb-rnd now
allows netlists to be allocated to electrically connected objects,
potentially assisting reverse engineering if your schematic editor supports
back annotation/netlist import.

4) use the above method (3) with photographs of a board.

5) attempt conversion of the binary files. Not easy and not quick if there
is no file format specification.

Regards,

Erich
