IDS Training Manual Wanted

I’m looking for a copy of the original training manual for the IDS. Does anyone have one they are willing to share? I have the one that refers to IDS & SDD but it is mostly about SDD. Before Jaguar thought of SDD, there must have been a technical manual for IDS on its own.

If have been using IDS 118.5 for a while so I know some of things it can do but I think there are features that I haven’t discovered.

Thanks for any help.
