I recently found an old computer, HP Logic Analyzer 1650A, in the trash. I took it home and it was working fine, except the floppy disk from -87 with the operating system was dead.
I decided to see if I could connect it's monitor to my Pi. Please look at the pictures below and help me determine what kind of interface I'm dealing with and how I can make the connection.
The monitor is black and white as far as I know, only seen the checking at boot (RAM, Disk...).
In picture 7-8 you'll see a flat ribbon cable with 20 pins. It says "input" at its connector on the monitors motherboard (the vertical one). Thats the only connection between the two motherboards and I think I have to use that cable somehow.
