Old Retro NEO Console on flea market !

found this console from the 90s, but with a strange name called NEO!
I didn't even think about it and bought it quickly, but unfortunately it has some problems!
This is not a problem, so I tried to defacto it and see if it can be repaired and cleaned!
I invite you to watch this experience together!
And my question is: WHAT IS NEO?
