Re: Need people to check my SBC design.

Again, thank you. I just implemented those changes into the project.
My plan for the UART was to hook up one of my ports to a MAX 3100 and use that with an Arduino to connect to my computer kind of like this: https://coronax.wordpress.com/tag/max3100/

Re: Need people to check my SBC design.

Thank you.
1. I NANDed the clock and RWB to get a read enable, then inverted that to get the write.
2. I now have all the unused gate inputs connected to ground.
3. That's now fixed.
4. I cant believe I messed that up. I think they're good now.
5. I've never used a pullup resistor, but I think that ...

Need people to check my SBC design.

Recently I've started designing a PCB for my 65(C)02 project that I'm working on. I've never done anything of this type, so I want someone to check my design to make sure that it will work before I order the circuit board.

Can I just connect my CPU (W65C02S) clock up to the 65C22

I'm sorry if this is a noob question, but I personally can't find an answer other than maybe following wires on a C64 datasheet.
I'm trying to make a simple 65C02 breadboard computer with nothing more than the CPU, some RAM, and an EEPROM. I decided that instead of using AND gates and a decoder for ...
