Learn more about the Soemtron on https://soemtron.org That's where I got all the schematics and information I used for restoring the device.

The stream ended abruptly because of power loss in my neighborhood, all went dark for a few hours. I managed to put the keyboard back together using a flashlight as a light source. Restoration will be continued in another video. Still got to edit the parts I already recorded.

Next one will sound better and louder :)
