Please do NOT judge the current version of the modeler by the content of that ancient page ...
(which BTW I have just deleted so it is no longer accessible).
I revived an old website in conjunction with the current modeler release & basically forgot that old page was still there.
That was a description of an earlier version of the modeler that ran only on the Kyma Capybara - which is out of production.
That was late 90s/early 2000s technology.
Take a listen to the current version if you are interested in modeling.
Cheers,
Rob
