Old Raytheon R10 cable

[HMcClard]

I have a Raytheon R10, not R10X. I'm trying to build a cable but can't find pin connections other than the dome connections in the German version R10 manual on the Raymarine retired manual site. Nothing close in the English files. Does anyone have the connector pin assignments? I have the dome colors from the German manual but that manual does not give any info about the connector at the display. Thanks in advance (and, yes I know this is an antique system but it DID work great until the cable got lost.
