Hello! firstname.lastname@example.org wrote: > I understand. What If I forget the CPU emulation and want to build only some RAM, ROM and one or two 8bit bi-directinal I/O ports, all available for the original CPU to interact with - what would you suggest? Can one easily make such structures (RAM, ROM, I/O port) available for 6502 from within a CPLD/FPGA and which would be "better" in such case? ROM and RAM are costly in terms of re-programmable logic. If you need these, you will end up using a FPGA anyway. If you need only I/O, then you can use a CPLD as well, there are still 5V ones available (though more expensive than 3.3V). Regards, Michau.
