Quote: What? No MMU? One of my favorite MMU’s is the MC6829. I have a few 74HCT612's on order. I need a MMU after all, just for kernal and user space. Page Zero size is 512 bytes, I have to write the new micro code to check if using pals as roms works. With the MMU I may get 3 mhz, but this just ball park for now, with the chips I am using. After I get the schematic roughed out,I may just brute force the disign to 36 bits by adding a second 16 bit alu. I guess a 8"x10" card will fit chips, not sure about the routing yet. |
