The prototype was constructed using point-to-point soldering with 30-ga wire wrap wire.  It was all done under the inspection microscope.  There are not many connections, but they are rather tedious so I can only do a dozen or so wires per session.  It took me 2 days and several hours total to finish the prototype board.
