Habe eben das hier in den Lynx FAQ´s gefunden:
Q. I hear there was a ComLynx port on the Atari Jaguar. How did that work?
Could I connect my Lynx to it? Was there a Lynx adaptor for the Jaguar?
A. The Jaguar does not have a ComLynx port per se, but has a ComLynx signal
on the system bus. An expansion port add-on would have made the port
available, and developers had announced plans for such accessories. It is
possible to daisy-chain multiple Jaguars for multiplayer games into a
"Jaguar network". In theory, it would have also been possible to connect
Jaguars and Lynxes, though no plans for cross-system software were ever
finalized.
There was also talk that the Jaguar's ComLynx signal could allow Lynxes to
be used as peripherals: software could have been developed to allow Lynxes
to be part of a Jaguar game as "smart" controllers. Again, no actual
plans were ever announced.
An adaptor to allow the Jaguar to play Lynx games was never planned.
