The more resources, the better. Just be aware that this book has the NMOS limitations and does not take advantage of the 65C02's bug fixes and extra instructions and addressing modes.

Very true on the NMOS version which the coding in the book is based on. However, I've used this as a guide mostly, more for ideas and always write my routines and look to leverage C02 opcodes and addressing modes as they can improve either performance, size or both. In short, I would never go back to the original NMOS instruction set.

Thanks a ton for the link, and thanks a ton Garth for the heads-up.

Here's where we are now. I have a working monitor that reads addresses, writes to them, and runs at them. In the example below, I just run at 8000 to restart my monitor. My syntax is a little strange, but it works for me. The video is below.

I plan on later adding in the function to automatically step to the next address if I don't press anything for reading, and same for writing. I will probably just precede that with a space so " FF" would write FF to the next location, just like the assembler on an A2E.

Looks good, Nick! I feel a bit sorry for your Enter key, though ... it sounds like you're mashing the s**t out of it.

Haha. When I watched the video back for the first time I heard that and thought "Wow I need to relax with the enter key." Typing one hand with a camera in the other....sorry enter key.
