[NLRS] Looking for information.

[Dr. Gerald N. Johnson]

At an estate sale of a ham today I acquired a RF source based on the 
AD9850. This particular one seems to have a port for a keyboard, 
multiple buttons, a LCD display for the PIC controller chip, a port for 
an encoder and many options.

There are pictures and a fractured web page of data at:

is more friendly but with fewer pictures and describes many of the 
connections but not where they are on the board or
the connectors. It came with cables terminated with connectors, but open 
ends at the other ends. Does anyone know of more detailed information 
like application schematics?
