Bob - you need to read the thread again - it relates the steps she used to try to get slides out of the film. She only used C41 as an initial check to see if the film will develop any colour.
She does predict, however, that it might behave better in low temperature C41.
Anscochrome 100 is from the mid-60's. Ansco used the Agfacolor principle to make their films. They also need respective processes. In case you cannot find a Ansco formula for processing it, try the the respective Agfa process.
