[hpsdr] Ozy/Janus Operating Manual available for download

[Thompson_Peter at emc.com]

Joe,

Thanks for the replies.

I have the parallel cable that originally shipped with my SDR1K (I've
never used this since I normally use the usb/parallel cable).  Is this
parallel cable a full 25 pin config and suitable for use between ozy and
the SDR1K?

Pete, N3EVL
