[Elecraft] K3 K3DSPUPGD Installation info?

[Terry Schieler]

I can't seem to locate any info on the installation of the Revision D
K3DSPUPGD DSP board on the Elecraft web site.  Is it not available until you
actually order and receive the upgrade board?  If it IS available as a
download, I'd like to review it before ordering.  Can anyone please help
point me toward the installation instructions?

Happy New Year!
