I've see it mentioned in several places that the "Westchester design" of the
A2000 will have additional signals available at the video slot, while the
"German design" will not.

In particular, the "Westchester design" is supposed to make available the 12
raw RGB bits, which would then permit add on boards to do things like "Chroma
Keying", in addition to "Genlocking".

Is this correct, George?  How can one tell if one is getting one design or the
other?  Are there yet other signals that the "Westchester design" provides in
addition to the raw RGB signals?


On a related topic ... when and where can one get the technical specs, etc. on
the A2000?
