Hi Carl,
Not sure if it's of any interest but I still have the three Yoocnc controller boards I removed from my 6040 when I replaced them with a Gecko G540.
You're welcome to them if you want them. One axis was a little flaky but I never tracked it down due to the controller update.
Drop me a PM if you want them and I'll get them in the mail.
