I have tested this for about one hour with a Commodore 64, plugged in with no issues.
It’s old, but it does work.
I can’t guarantee it will work for the next 40 years.
Please see the video that shows all the features working.
I have not tested the speakers. Everything that I found in the house clearance appears to be working, so I guess the speakers should be okay too.
