In the model block on the system page all it said was 788. It's a 788ci (no HD DI) model. The other unit is a 998c si. I can give you the serial numbers also if you need them.

The 788 software is 4.780, and the 998 has 4.970. The 788 will comm. with the interlink and the 998 won't (now). "Synch. failed-participation canceled"

The 998 has synch'd and exchanged points before now, a couple of different times.
