If you look at the RZ1 schematics you will notice that the RZ1 RAM chips have two chip enable inputs (CE1 and CE2). The SK8, MMT8 and modern RAM chips have one CE input (active low) and in the place of the CE2 input they have an address input. So I think that this mod is undoable. Please share your thoughts..
