[casper] Gerbers for ROACH

[Rich Lacasse]

On the CASPER web site, there is a link for Gerber files and a link to 
get a PADS PCB viewer.  I wanted to have a look at the board layers so 
gave this a try and ran into two problems.  First, the "Gerbers" are not 
a standard gerber file, viewable by the gerber viewers I already had.  
Second, the downloaded product from Mentor complained that the file I 
gave it to look at, (top silk screen layer) was not compatible with the 
current version of their viewer.  Any advice on how to view the various 
board layers?

Thanks,
Rich
