Hi Al --

The resolution is impressive.  It was made using a 600dpi printer.  He used
mostly surface-mount parts with a few through-hole parts.  But his layout
planned that the holes weren't going to be plated through and used
"z-wires" to connect traces top-to-bottom where needed.  Using wire-wrap
sockets for ICs allowed the sockets to be spaced up off the board for
top-side soldering.

Also impressive is the ease with which a board can be made.  If something
doesn't work out right, you can just change it and make a new board with a
turn-around time of a couple of hours.
