Help identify these addons pcb

From the look of them, they are multi Operation System ROM's , the switch at the top will select which one.

However exactly what OS's they are will depend on the ROM contents.

 

They probably won't work as it appears 2 logic chips are missing from the addon board, but you never know

they may only be required if the 3rd ROM socket is occupied (seems odd the same chips missing from both boards).

 

Maybe someone has one of these and can advise further.
