Hello Greg, Unfortunately Stephen already unsubscribed. I reached out to him, but got no response.
As to the pin alignment, I'm glad you got it working. Sometimes debugging issues is a matter of faith. If you aren't sure what part to trust, you end up chasing your tail. I have a strong level of confidence in REX at this point given Stephen Adolph's design, firmware and software, and it's unlikely any of the people currently shipping them would ship them untested. So I think the #1 default culprit is going to be pin contact since that's the random variable. Even if it leaves the fabricator's workbench fully tested, which I fully expect they all do (since who would want to deal with tech support issues) they can't know what condition the customer's option ROM socket is going to be in. And it has proven in practice to be a common issue in installing REX. I had the same problem installing my units. Luckily it's not too hard to bend the pins back out a bit to make contact. -- John.
