Thank you for the informations,

I have unplugged the cards from the board,
reattached them and - it works (partial)!

I have a DOS 3.3 original Apple Disk in the Drive 1 (S6,D1)
but the only - but hopefully - change is a nice "APPLE ][" on the
orange Phillips screen. The Disk drive starts to run, the red LED is
glowing straight, the Disk is cycling - but not booting...

I tried a few DOS Disks - no booting at all.

Any idea?
