Hi Guillaume,
Looks most like a "Base64" ][+ compatible mother board, with the 6502
and Z-80 on board.



    Okay, I'll have more answers when receiving it.
    But every comment will guide me in my investigations.



You seem to be missing the ROM riser card though!!!!!
Should be a small, half-height card with one or two roms/eproms on it,
which plugs into slot # 0.



    Here it is:

    But why are there four Roms places?
    One is clearly labelled F0-F8 Apple (Prodos)
    And I think the other one is BASIC 8K, but I might be wrong.


I'd guess that the card is set up to accept ROMs of different
sizes, so there are more places for ROMs.

In the photo, one ROM is 4KB, replacing the F0 and F8 ROMs, and
one ROM is 8KB, replacing the four (D0, D8, E0, E8) Applesoft ROMs.
