Well... after the little demons fall asleep, i can do the tests...
First i tried changing the monitor, then tried changing the hercules card. The problem was SOLVED.. but, a new mistery arrived...
With this Hercules clone card, the one that was in the machine and has the flickering

At this point i have second thoughs... why now is working on the Samsung Monitor??
Conclusion... ¿?
I will use the other hercules card, because i love the ambar hercules screen. But the hercules card that made the flickering on the ambar monitor works perfectly on the white monitor...
I don't know why.. 😠
Now i can play prehistorik.. but the mistery remains... 😕
