I got an one Amiga 1200 mobo recently and of course without any kind of case or keyboard. Since I got many dead/zombie Amiga 500s around here I wounder if I could use 500 keyboard on 1200. I know that to use 500 keyboard controller on 1200 needs some solder hack on 1200 mobo but are 500 and 1200 keyboards in other ways fully compatible (keymapping etc.) ?
