Thanks to all for the replies. The mobo runs ok except the floppy drive, and the mouse port. I'm using at the moment a joystick extender in order to get two ports on the joystick port and allowing me the use of a mouse with the setmport utility. The psu is ok, i'ts an at pc generic one and is delivering the correct values. I suspect the controller was broken because the port failure and the problem with the drive. Also it's interesting that i have an external amiga drive and it doesn't get recognized as well. Seems that i need to find another mobo, but recently searching for a 1200 board at good price has been difficult.
