Yes,

The DOS circad I've been using has 16 drawing layers. So the BOARD 
layers might be as few as 8 or as many as 14...

I forgot to add that the DOS version is now about 600 bucks. And it 
includes the ability to output for trace isolation milling directly.

Also, in the windows version you can import a bitmap and run traces 
and pads "on top of" what you've pulled in with the bitmap. Makes 
reverse engineering nice and easy.

This brings up something I've been wondering about Eagle... Can you 
create a schematic from the board layout?  

Thank you in advance,

Ballendo
