can anyone document how to add the 256kb as piggy back on the existing 256kb pcb chips instead of thru the ram expansion socket - is there any way to adapt the internal ram expansion into thinking it has some external ram - no matter how small or rom area ram like the +disciple/multiface? MMU like mb-02+ dma in there somewhere pentagon style ram? only a thought... how much do you want for it where abouts are you?
