I went to their web site: www.uascwa.com and found info on the newer models; UNS1-F,E, and L. I didn't see anything on the A,B, or C models.

Maybe you could contact them for more info.

Just got back from the Universal factory in Tucson. Read your post before going, and asked them your question. Here is what the instructor said:

UNS 1A-- Museum Piece
UNS 1B-- Museum Piece

UNS 1C, 1D, 1K-- was "state of the art" till a couple months ago
600 series software
Zilog Microprocessor
8mb ram (cant hold whole world, but they can customize "the world-- ie we only have world with 5000ft+ runways)

UNS 1D is two box installation (E&E and cockpit)
UNS 1C same stuff, one box (cockpit only)
UNS 1Csp "Short Package" (smaller case) if you have an all digital aircraft.

UNS 1K is two boxes, and a scaled down, smaller cheaper version of the 1c/d.
Smaller screen and keyboard (for smaller install space)
A few less features, but functionally the same more or less
-- not video capable (airshow, upload weather)
--not TAWS (terrain awareness) capable

The Latest and Greatest from Universal:

UNS 1E-- Like the UNS 1C
UNS 1F-- Like the UNS 1D
UNS 1L-- Like the UNS 1K

E,F,L Changes:
Motorola Microprocessor
16mb+ memory
Active Matrix LCD display
Ethernet loader (make disk loads way quicker)
800 Series software, which supports new features
--GLONASS (soviet GPS)
--"Abeams" Points

1C, 1D and 1K can be upgraded to the 800 series software, becoming 1C+, 1D+, 1K+. Screen might be upgradeable to the active matrix also (depends on s/n).

System Software:
6.xx The normal C,D,K stuff
7.xx C,D,K stuff with tactical/SAR features (patern search ect)
8.xx E,F,L software
9.xx E,F,L Software with tactical/SAR features

Hope that answers all you want and then some!
