Interakt's Old Extensions Question

[ll]

I'm interested in developing with Interak's KTML, as well as the other
tools that they offered.  I understand that they were bought by Adobe,
and that the official site no longer offers the product, although
there did used to exist free trial versions of the product.
Does anyone know if those free versions still exist somewhere on the
internet?  I've been trying Fck editor, but I would like to try both,
side by side, in my dev.
Many thanks,
Louis
