6809 SBC for Externally Clocked 6809

Needed to test a few 6809E cpus , and try writing some 6809 code. Found this nkce project on github. Assembled one board , the project has a slight issue , the two serial ports are wired one DTE and one DCE , this caused me a little confusion. I also forgot that 6809 boot vector is at the top of memory , so needed to place boot code at the last addresses in flash. Enjoyable project.

    The part turned out fantastic. The gold color is very close to what I was looking for. The cost in quantiles is very good as well. Here is a review video I did on YouTube. https://youtu.be/9yMbxceadB...
