I have a fully working space invaders board which when I hook the pod up to and do Run UUT doesn't, it starts up and crashes.
Pod passes self test.
Anyone ever done this?

Try a faster 8080 CPU in the pod, or try substituting the 8080 from the game in place of the pod CPU. It is possible the CPU is bad or slower than the system can handle. Do you have the flat ribbon cable from the pod to the CPU socket or the twisted pair cable? The twisted pair cable handles noise better and will work in situations when the simple flat cable won't, plus it can be longer as a result. David, I have no idea why this did not show up in TTL - you are subscribed under the same email address as you posted here. I haven't seen any bounces for your email address.
