I have a customer with a CICS 2.0 Expanded. They are looking to purchase a 7406E. I've looked over the Norstar Compatibility Guide and can see that a 7406 will be compatible with a CICS 2.0, but I can't see where the 7406E fits in. I've been burned by the 7316 and 7316E aren't always similar in their compatibility. Looking to see if anyone knows how far back I can take the 7406E set.
