Hello all,
Although this is certainly elementary, I thought I'd share it since it may help someone in a pinch; here is my simple technique to create a preliminary schematic from a populated 1 or 2 sided pcb:

Sorry, I used the internal domain name on the lan, it should be

People do weird things. BTW, your "revised" posting has the incorrect URL in it again! The link above works, of course...
Michael Grigoni described his method of PCB reverse engineering
I used a similar method: taking a picture of the trace side, editing it, flipping and possibly superimposing a photo of the component side. I then use a circuit drawing program such as Dia (it's native on Linux but has been ported to Windows, too:
Because the diagram program maintains the connectivity when elements are moved around, I can rearrange and straighten up the topology of the schematics, rats-nest like. If one could import background into a proper PCB design program such as Eagle, one should be able to get back the PCB.
gEDA's PCB had this feature in the Xaw version; we haven't gotten around to re-adding it in the latest version.
