I'm using the amis editor from the archives on trailing edge, which works very well. It's source language is pascal, but it seems to be some branch of the pascal family that is not known to trailing edge.
This leaves an excellent resource in a precarious state - usable but incapable of being fixed or improved.

a) so if anyone knows the who/what/where if the pascal used for Amis?

b) I've rescued my own version of pascal, the result of a couple years of off-and-on hacking of the old decus(vintage 1977) version. I could make test distributions to anyone interested in vintage pascal.
