I built mine

 Did you use that directly with ExpressPCB and order from ExpressPCB or did you convert to
more standard gerbers? 
 I just went with ExpressPCB for minimal hassle, but you

which run asynchronously, it was handy to build up two of these.  Also useful for the
RK11-C.

I have Joerg Hoppe's KM11 bare boards available.
He also has gerbers available at
