This may not look like much, but this is the makings of 64kb external SRAM, 6502 emulator. Now I understand why early computers had indicators for the address and data bus. My goal is to emulate an apple II slots and all. The CPU should be cycle correct, though runs at about 4mhz. I didn't write the 6502 cpu emulation, I just modified it to work with external memory. Eventually I would like to stick this into a vintage case with a disk drive, video, keyboard and see if anyone can tell.
