Homebrew PCBs

Yahoo groups is really iffy on posting these days.  Anyway here it is 
again:

The website I put up a while ago shows just such a usage.

http://myweb.cableone.net/wheedal/pcb.htm

uses a 100 pin TQFP Xilinx CPLD as a TT demonstration.  The part 
is .5mm or 19.685mil pin center to pin center.  Works good, have done 
it *many* times since the first posting.
