Yesterday I found a stack of my old mid-90's sdks, ddks, and msdn discs.
I'm starting to search them now....
Edit: I found Vfw1.1e from late 1994, but it is too new. Because of the big lawsuit with Microsoft, Intel, and Canyon, all DCI samples were scrubbed and DCI was on the way out.
We need to find Vfw1.1d from before September 1994.
