I did "try" to the extent of starting to do a layout on a small bit of board,  
and it was such a PITA that I decided against the idea of finishing it.  And 
this was a few years ago,  I doubt that I'd have *more* patience these days.

So that bottle of etchant is sitting somewhere in storage.  Seeing as how 
somebody mentioned a limited lifetime for those bottles (the stuff actually 
starts to eat the bottle after a while!) I probably oughta find it,  before 
it makes one hell of a mess!  :-)
