The addressing of the SW ROMs in the Exp.Mod.3 is probably the same
as for the center-slot 4-ROM French or German SW cards (in European ADAMs;
the traces are not connected on North American ADAMs so the cards won't work),
4 8K ROMs. Though one of the ALF chips would have to be 16K, right, to hold
the 8K EOS ROM? I have never opened up an Exp.Mod.3 so I don't know what it
looks like in there...
