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.
