[Premium-Rx] RA3791 OPTIONS?

[Pat1McA at aol.com]

Hello to all,
 
Does anyone possess a list of  Racal RA3791 Receiver Eprom software  
version numbers against their functionality and option level?
 
I have a receiver here with four DSPs fitted, one is a  complicated noise 
blanker, but there is no mention of what Option  number this is.
 
It does seem to be particularly difficult  to "decode" this  series of 
Racal receivers' functions.
 
Please reply off line - many thanks,
