Hello,
some years ago a aquired a HP-41CV. Also in the box was a HP-IL Modul HP82160A and a video interface HP82163B. I attached the HP-IL module to the calculator, the video interface to the HP-IL module and a monochrome monitor to the video interface. Then I switched everything on and at least I got a blinking cursor on the monitor. But there is no reponse on the monitor if I press some keys on the calculator.
Is there a simple way to test the video interface? Maybe there is some kind of echo function, which just shows everything I do on the calculator on the monitor?
Thanks for your help!
Ingo
