Hello, All I raised this topic in another section: http://zx.pk.ru/showthread.php?t=3616&page=1&pp=10 And I came to the conclusion that my yellow scorpion has a slow controller drive, because on my other board (green) the demo works absolutely right. Tell me how to cure it? Maybe some kind of microcircuit has gone bad? ;) PS; Ha; The board has Scorpio's signature turbocharged VG from TM2 to mounting field.
