| Mark and the group,
Here is the lineage of the original omni series as I understand it:
The first ones were simply called OMNI, and came in two readout 
flavors - A (analog) and D (digital.)
The next iteration was called OMNI B, and was also either A (analog) 
or D (digital.)
The final permutation was the OMNI C, and it only came as digital.
Tentec offered a retrofit to convert an OMNI nothing to an OMNI B.
So...are you thoroughly confused?  Me too.
