Working with an old Russian Electronika MC6205 neon dot matrix display. Trying to get it powered and connected to a computer.

Will eventually figure out something cool to do with it. But for now I just want to get it working.

Some time ago I purchased this MC6205 display on eBay.  I've been wanting to connect it to my computer and eventually build some sort of project with it.  It came with a wiring diagram to connect via parallel.  The display has an odd Russian socket on it but I was able to order the matching plugs on eBay.  I made a cable but when I powered it nothing happened.  I thought my cable was bad since It sure looks bad ;).  I designed an adapter board with onboard jack for 12 volt supply and regulator for the 5 volt supply.  After soldering and hooking it up nothing happened.  I tried again and waited a couple minutes and parts of the screen started flickering then the whole screen flickered a few times and then it came on.  It hasn't had issues starting since so it might have been a first time startup issue or an issue with sitting so long.  It currently displays a bunch of junk since I don't have the parallel socket to connect it yet.

I found some software to send text to it.  It's basic and I hope to reverse engineer the data it's sending to figure out how to write my own.

P.S.  The display is currently upside down, since the port is on the bottom.

Manual for the display (in Russian) Not much use to me at the moment. Might be a good idea to try translating it.

Gerber Files for the adapter board. Just upload and go.

MC6205 Software and Wireing

This is the software I found. I translated the readme to make it easier to install. (Note, I did not create this software, if the original creator wants me to remove it I can do that)

  • 2 × 10 uF Capacitors Make sure they can handle the 12 volts
  • 1 × CHO63-48/95x9P-24-2-8 socket Not sure if that is the actual part number.

I also have this screen. I made it work and everything is fine with me (I even wrote a program). I recommend applying 30A GND to the pin to drive the monitor out if it is junk.
If necessary, I can send my program code for arduino

Arduino code would be fantastic.  I've been having issues with the software side, mostly figuring out the control commands to send to the display.

I've seen pictures of it being used in a money counter for banknotes. I'll post a picture if I can find it again

On the device "BANKNOTA-1". cnc machine tools:
MAYAK-221, MAYAK-223, 2M43, KM43, 2S85, KM85. And one rare comp ... On Wikipedia it is written (Russian)
You can also look where they use IMG-1-03 is an indicator in the monitor
