RE: HP 82985A Video Interface Manual
The following link leads to the 106-page manual "HP82985A Video Interface Installation and Operating Instructions". It is in four languages, English, French, Italian and German.

Especially interesting I find the jumper described in it to adjust the interface to the respective mains frequency. I think it's about the fact that old monitors derived their refresh rate from the mains frequency: For example in the USA 60 Hertz and in Europe 50 Hertz. If you use this interface in Europe with an old monitor and the picture flickers or is unstable, then changing this jumper should help.
