[little update]
I tryed som configurations. But only one works with my DELL computer and Win 10:
Connecting the board with a PS/2-cable to the computer. Then connecting an additional keyboard to the I-Pac-board.
Jumpers are: MAME and PS/2
Jumpering ALT doesn't work
Jumpering USB (and using an USB/PS/2-adapter does'nt work
Using the board without an addition keyboard connected to the board doesn't work.
