A 7094 will run a 6105, that is the current equivalent. Do keep in mind that a 7094 would be nearing 10 years old itself and it could fail soon, this won't be because of the upgrade but simply because the relays and switches have a finite life, after so many cycles they can and do fail. The newer controllers are solid state and last much longer, I honestly don't see many 7094's that still work.
