In MMD 041021 Randy Hewitson asked where to get a Marantz Pianocorder
manual.  John Tuttle offers reprints of the Pianocorder manuals for
purchase through his Player-Care web site:

  https://www.buysecure.com/playercare/reprints.html

Assorted Pianocorder documentation is also available in PDF format
on one of the web pages I maintain:

  http://dp70.dyndns.org/pianocorder/doc.html

Bear in mind that the Pianocorder owner's manual is devoid of technical
information and is not very useful for troubleshooting purposes. The
Troubleshooting Guide and Field Service Manual are better resources.
