W65C02S Address selection

ElectroRetroNerd
ElectroRetroNerd over 11 years ago

Hello World! My name is Kaleb Papesh and I have decided to build my very own 6502 based computer from the ground up after watching the Apple 1 episodes of TBHS. I know that the 6502 is alive and kicking with Western Design Center currently making the chips however, after looking at the data sheets, I don't see any CS or CE lines for me to use a 3-8 decoder to select ram. Has anyone else used a W65C02S chip in there own 6502 based computers? I don't fully understand the entire addressing architecture for the 6502 so if anyone has in depth information on how it works and how to use a 3-8 decoder to select and use ram, the better! Thank you for any help you can provide!

    I still have my 6502 powered Commodore PET computer.

     

    The 6502 was an interesting chip, but unless you are really into nostalgia, there are just too many other modern chips that you could program to emulate the old 6502 software.

     

    Still, if you are diligent enough, you can rebuild the 6502 devices.

     

    Good luck.
