In the begining...
there was the Omni A (as in analog display) and Omni D (as in digital
display)...
followed by the Omni B which could also be made from an A or a D by
factory upgrade...
and finally there was the Omni C, with digital display only.
All this was followed by the Corsairs, Paragon, and THEN the Omni V.
But that's another story. It was fun work.
