@dukkko02 ,

Your topic was moved to its current location as it is more suitable.

Could you also take a few moments to Learn How To Use The Forum.

It will help you get the best out of the forum in the future.

Thank you

what kind of machines? do they just need to be turned on? What type of displays and how are they connected? An I2C bus could connect to dozens of complicated devices

6

Are the machines identical in both electrical and mechanical construction?

Do you have a question?
