    Nice demo! I was so impressed with Denis' ROM that I made a copy of his as accurately as I could muster, even including the red label. His still looked better than mine though. He had a video about it on his YT channel. He would be flattered if he knew you did this.

      Thank you! I saw his video and read through the comments and I saw that you were already digging into it over a year ago. I too am really impressed with his ROM. I'm sure your being modest because I've seen your work and you make some really good stuff so I bet your version looks and works great! :)

    Really cool!! I wonder if this step could be modified for other computers. Thanks for sharing!

      I don't see why it couldn't be used on other 6809 based machines and the idea itself can be taken to other machines. I know the commodore has something similar to this.

    So you're not just testing the ram , you are testing the data bus and some address lines as well....
