I did promise to follow up on this when I had resolved the problem. Although the jukebox ( City ES2) was on free play, the coin mech. was still connected and an issue had developed in it. I have had a problem in the past with a fault on the remote selection card which took me ages to find - just because I kept looking in the wrong places, so I usually now disconnect that at the CCU if it's not used. All these inputs tie into the same switch matrix so a fault on something that's not used can easily screw things up. One thing to be aware of is that there's an interposing circuit board between the coin mech and the CCU and disconnecting the coin acceptor plug at the CCU generates an error. The coin mech itself can be disconnected but the little circuit board which sits below it and behind the coin channel must remain connected to the CCU. So now I can program the EA ROM using the guide although for a free play machine, really only two locations are required since most of the programming deals with pricing. And at the end of all that, there was nothing wrong with the original EA ROM! Hopefully now Tony can be inspired to revisit his NSM!

I do have a good IC and a bad one, and a few new (new old stock?) and have swapped them and only the one works. I can check sometime, right now it's difficult to get to the "test machine".
