Connecting a Pi to an 80's monitor?

Thu Sep 27, 2018 1:25 pm

I recently picked up this vintage green-screen computer monitor from c. 1983, and I thought it would be fun to use it with my Pi and other devices.

How would I buy/build a video cable that connects a male composite jack to the DIN(?) socket on the back of the monitor?

First convert to VGA https://thepihut.com/products/raspberry ... -convertor

Then convert VGA to comp. sync http://www.epanorama.net/circuits/vga2rgbs.html

No idea if it will work but I would try command line first :D :lol: :D

My, 'try the simplest thing first,' approach would be to connect the composite video output from the 3.5mm jack on the RPi to the Composite In on pin 4 of the monitor.

That was going to be my response too. I'd connect the ground to the "earth" pin too.
Unusual connector... I thought it might be similar to the commodore 64's DIN connector but apparently not.

It worked! I connected pins 3 and 4 to a female composite jack and now it displays composite video! Now all I need is a 3.5mm to RCA adapter.

Here's a picture of my Super Nintendo plugged into the monitor.
