tex screen previewer for xenix

[David Jaffe]

Does anyone know of a TeX screen previewer which will work under Xenix 2.3.2?

Incidentally, I have installed TeX from the public domain source code.
I have detailed instructions if anyone wants them.  A couple of other people 
have indicated that they have done this.
