Building RC6502 - how to test its all working?

[gmc]

I've just built the RC6502-Apple-1-Replica PCB and populated with all chips (RAM, ROM etc)

Project link:
https://github.com/tebl/RC6502-Apple-1- ... %201%20SBC

Just fired it up and connected up a USB to the Arduino and it looks like its all working.
Wrote a quick hello world program which works.

My question is now before I pat myself on the back how can I see 100% sure everything is working as it should. Like for example how can I test the RAM is working as expected. I'm guessing the ROM works as it contains BASIC and the small program I run works.

Is there anything else I should be checking, and if so how can I test it?

You may also find the following book useful... it contains many useful routines and was written using an Apple II. I still have my original hardcopy book, but the PDF version linked here is nice to have:
