There is a version of ppchtex in context. In TeX Live one inputs
m-ch-en.tex (for English interface) or m-ch-de.tex or m-ch-nl.tex.
These input ppchtex.noc, which then inputs ppchtex.mkii.

Since, m-ch-en.tex is located in tex/generic/context/ppchtex/ , I assume
it is meant to work in plain TeX. Unfortunately, I cannot find any
documentation (and comments in the file are in Dutch), so I cannot say
how it is meant to be used. It seems to be based on pictex and pstricks.


Good luck,
