It was like a zillion years ago, I cant remember exactly, but I seem to recall I download it from over there. I am sorry, my braincells are not that good anymore

Sage was more like a library with a huge set of functions that mainly supported gfx cards based on the TMS3xxxx chipset.
I remember the Harlequin, Rembrandt, Resolver, Impact Vision 24 and Opalvision were supported.
