HI, yes i think so. Most external RAM cards use the same chip...i can name numbers of examples so why should this be different. ;) just copy the part of the internal ram circuit going to the cpu. Just adding only an extra chip wont work, it will need some extra circuitry to adress the ext. ram chip. There are schematics available of the Siel DK80 ram card...it uses the same ic. Maybe it will help you ikndentify the other circuitry concerning the SDS.
