I bought most of the chips from ebay. I'm sure the SAM and CPU are used. So in order to test them I built a simple computer with a serial port that runs basic. This is based on Grant Searle's design and uses firmware from Jeff Tranter.

I built this on a prototype board using point to point wiring. Not pretty but it works!

This design proved that the 6809E (and 6309E) are working
