Is there a good overview of the engine diagnostic functions in a 1994 850 GLT engine somewhere online?

Do you mean when you use the diagnostic port under the hood near the power steering pump? Do you want to know how to use it or what the codes are telling you?

Yes, the little pin connector you put in different holes for readouts. Preferably both how to use it and what the codes mean.

It should be in repair database.
