I do recall that a friend built the PW and reported to me that he 
thought it was the worst modem he'd ever used.  I was happily using 
my scavenged-from-a-TI-terminal modem.  I mounted it with a small 
power supply in one of those hammertone Bud aluminum utility boxes--
and used a 4-conductor "Jones plug" for the signal lines.
